How do you make a whore moan?

Extract sapogenins from a Mexican yam and employ Marker degradation to degrade the sapogenin side chain while leaving similar functional groups on the steroid nucleus (relatively) unaffected. Use acetic anhydride to block the hydroxyl group formed by opening the six-membered pyran ring. Then oxidatively open the five-membered furan ring with chromic acid. This forms the acetyl side chain of progesterone and an esterified hydroxyl group on the steroid nucleus. The ester is then hydrolyzed under strongly basic conditions. The use of acetic acid leads to the production of 16-dehydropregnenolone acetate (16-DPA). 16-DP can be converted into progesterone in two steps. Firstly, the double bond in ring D is hydrogenated, followed by Oppenauer oxidation of the hydroxyl group and the concurrent migration of the remaining olefin from ring B to ring A so that it is in conjugation with the ketone carbonyl group at position 3. Alternatively, a three-step procedure involving Br2, CrO3, and Zn/HOAc can be used. 16-DP can also be converted into testosterone and the downstream products estrone and estradiol. 👍

🔬🌀Demystifying the Krebs Cycle: A Deep Dive into Cellular Respiration! 🌀🔬

Prepare for a thrilling journey into the heart of cellular metabolism! 🌟✨ Today, we unravel the intricacies of the Krebs Cycle, also known as the Citric Acid Cycle or Tricarboxylic Acid Cycle, a cornerstone of energy production in our cells. 💡🤯

The Krebs Cycle: Named after its discoverer, Sir Hans Krebs, this metabolic pathway occurs within the mitochondria and is a central hub in cellular respiration.

🔍Step 1: Acetyl-CoA Entry

Acetyl-CoA, derived from the breakdown of glucose or fatty acids, enters the cycle.

It combines with oxaloacetate to form citrate, a six-carbon compound.

🔍Step 2: Isocitrate Formation

A rearrangement converts citrate into isocitrate.

The enzyme aconitase facilitates this transformation.

🔍Step 3: Alpha-Ketoglutarate Production

Isocitrate undergoes oxidative decarboxylation, shedding a CO2 molecule and yielding alpha-ketoglutarate.

NAD+ is reduced to NADH in this step.

🔍Step 4: Succinyl-CoA Synthesis

Alpha-ketoglutarate loses CO2 and acquires a CoA group to form succinyl-CoA.

Another NAD+ is reduced to NADH.

This step is catalyzed by alpha-ketoglutarate dehydrogenase.

🔍Step 5: Succinate Formation

Succinyl-CoA releases CoA, becoming succinate.

A molecule of GTP (guanosine triphosphate) is generated as a high-energy phosphate bond.

Succinate dehydrogenase is pivotal, transferring electrons to the electron transport chain (ETC).

🔍Step 6: Fumarate Generation

Succinate is oxidized to fumarate with the help of the enzyme succinate dehydrogenase.

FADH2 (flavin adenine dinucleotide) is formed and transfers electrons to the ETC.

🔍Step 7: Malate Formation

Fumarate undergoes hydration to form malate, catalyzed by fumarase.

🔍Step 8: Regeneration of Oxaloacetate

Malate is oxidized back to oxaloacetate.

NAD+ is reduced to NADH.

Oxaloacetate is ready to initiate another round of the Krebs Cycle.

The Krebs Cycle - an intricate dance of chemical transformations fueling the cellular machinery of life. 🕺💃 Dive deeper into cellular respiration, where molecules tango to generate ATP, our cellular energy currency!

Cellular Respiration ₊˚⊹♡

Cellular Respiration - a series of chemical reactions that convert the chemical energy in fuel molecules into the chemical energy of adenosine triphosphate (aka ATP)

converts chemical potential energy in organic molecules to chemical potential energy in ATP

Chemical Reaction: C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy!!

Why does cellular respiration produce a large amount of energy?

The sum of the potential energy in the chemical bonds of the reactants (glucose and oxygen) is higher than that of the products (carbon dioxide and water) Because of this, a lot of energy is released

Note: energy is not released all at once, but in a series of chemical reactions!!

How is ATP produced?

ATP energy is produced in 2 ways!

substrate-level phosphorylation - an organic molecule transfers a phosphate group directly to ADP (adenosine diphosphate) to make ATP

oxidative phosphorylation - the chemical energy of organic molecules is transferred first to electron carriers which transport electrons released during the catabolism of organic molecules to the electron transport chain. through this process, they harness the energy used to make ATP.

(there are more notes, but i'm currently a lil too lazy to write them!!)

brief summary of things I still need to learn:

NAD and FAD

4 stages of cellular respiration

1 - glycolysis

2 - pyruvate is oxidized to another molecule called acetyl coenzyme, or acetyl-CoA

3 - citric acid cycle

4- oxidative phosphorylation

Histone Modifications

Hello, hello! Today's topic is histone modifications. We are continuing on with the epigenetics theme after my previous educational post about DNA methylation. As described in that post, epigenetics is the study of heritable genetic modifications without a change in DNA sequence (Takuno & Gaut, 2012). Similarly to DNA methylation, histone modifications affect gene expression through regulation of accessibility of the DNA for transcription (Bartova et al, 2008). But before we get into these modifications, let's go over a bit of background information!

What is a histone, anyway? A histone is a type of protein involved in DNA compaction and organization. In order to fit a genome's worth of DNA into the nucleus of a cell, that stuff needs to be extremely tightly packed! Histones help with this by forming an octomer called a nucleosome, which the DNA wraps around. These nucleosomes then coil together to form a fiber known as chromatin, which goes on to make up a chromosome. When the chromatin is less tightly packed, it is known as euchromatin and it is available for transcription (Bartova et al, 2008). When it is more tightly packed, it is known as heterchromatin, and polymerase proteins cannot access and transcribe the DNA (Bartova et al, 2008). Histone modifications regulate the transition between heterochromatin and euchromatin (Bartova et al, 2008).

(Above image from humanoriginproject.com)

(Above image from Caputi et al, 2017)

The octomer core of a nucleosome is made up of two copies of each of four types of histones: H2A, H2B, H3, and H4 (Marino-Ramirez et al, 2017). Each of these histones includes an N-terminal tail structure, which is the main site of modification (Marino-Ramirez et al, 2017). The tails are modified through addition and removal of certain functional groups or other small structures. Types of modifications include acetylation by histone acetyltransferases, methylation by histone methyltransferases, phosphorylation by kinases, and ubiquitination (Marino-Ramirez et al, 2017). All of this information is used for naming specific histone modifications: Which histone is modified, which amino acid of the histone tail the modification is on, what type of modification is made, and in what amount. For example, H3K9me2 is the name for di-methylation of the 9th Lysine on an H3 histone's tail.

Some important histone modifications and their effects include:

H3K9me2: transcriptional activation + maintenance of CHG DNA methylation in plants

H3K9me3: transcriptional repression

H3K9ac: transcriptional activation

H3K4me1 & H3K4me3: transcriptional activation

H3K27me3: transcriptional repression

H4K16ac: transcriptional activation

H3S10p: DNA replication-related chromatin condensation

(He & Lehming, 2003)

Important Terms: histone, nucleosome, heterochromatin, euchromatin, transcription, epigenetics

Lewisite (L) (A-243) is an organoarsenic compound. It was once manufactured in the U.S., Japan, Germany[2] and the Soviet Union[3] for use as a chemical weapon, acting as a vesicant (blister agent) and lung irritant. Although the substance is colorless and odorless in its pure form, impure samples of lewisite are a yellow, brown, violet-black, green, or amber oily liquid with a distinctive odor that has been described as similar to geraniums.[4][5][6]

Apart from deliberately injuring and killing people, lewisite has no commercial, industrial, or scientific applications.[7] In a 1959 paper regarding the development of a batch process for lewisite synthesis, Gordon Jarman of the United States Army Chemical Warfare Laboratories said:

The manufacture can be one of the easiest and most economical in the metal-organic field, and it is regretted that no one has ever found any use for the compound. It is a pity to waste such a neat process.[7]

Lewisite is a suicide inhibitor of the E3 component of pyruvate dehydrogenase. As an efficient method to produce ATP, pyruvate dehydrogenase is involved in the conversion of pyruvate to acetyl-CoA. The latter subsequently enters the TCA cycle. Peripheral nervous system pathology usually arises from Lewisite exposure as the nervous system essentially relies on glucose as its only catabolic fuel.[10]

In biochemistry, suicide inhibition, also known as suicide inactivation or mechanism-based inhibition, is an irreversible form of enzyme inhibition that occurs when an enzyme binds a substrate analog and forms an irreversible complex with it through a covalent bond during the normal catalysis reaction. The inhibitor binds to the active site where it is modified by the enzyme to produce a reactive group that reacts irreversibly to form a stable inhibitor-enzyme complex

Pyruvate dehydrogenase is usually encountered as a component, referred to as E1, of the pyruvate dehydrogenase complex (PDC). PDC consists of other enzymes, referred to as E2 and E3. Collectively E1-E3 transform pyruvate, NAD+, coenzyme A into acetyl-CoA, CO2, and NADH. The conversion is crucial because acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration.[2]

it stops your cells from performing cellular respiration! by permanently breaking the enzymes! so fucked!

Why is epigenetic regulation important?

Epigenetic regulation is a complex process that controls gene expression and plays a crucial role in the development and maintenance of an organism. Epigenetics refer to modifications that alter the structure of DNA without altering its sequence and therefore influence how genes are expressed. These modifications can be passed down from generation to generation and influenced by environmental factors.

The function of epigenetic regulation is to control which genes are turned on or off and when they are activated. This is important because not all genes need to be active all the time, and different cells require different subsets of genes to be expressed. For example, skin and liver cells have different functions and express different genes. Epigenetic modifications play a critical role in this process by regulating gene expression.

One of the most well-known epigenetic modifications is DNA methylation, which involves adding a methyl group to a cytosine base in DNA. Methylation often occurs at CpG sites, where a cytosine base is next to a guanine base. When these sites are methylated, they can prevent the binding of transcription factors, which are proteins that bind to DNA and activate gene expression. As a result, DNA methylation can silence genes and prevent their expression.

Another important epigenetic modification is histone modification. Histones are proteins that help package DNA into a compact structure called chromatin. Histone modifications, such as acetylation, phosphorylation, and methylation, can alter the structure of chromatin and influence gene expression. For example, acetylation of histones generally promotes gene expression, while methylation can either promote or repress gene expression depending on the location and degree of modification.

Epigenetic regulation also plays a crucial role in development. During embryonic development, cells differentiate into different cell types, such as muscle or nerve cells, and epigenetic modifications help determine which genes are expressed in each cell type. Epigenetic changes can also occur during development and affect gene expression later in life. For example, exposure to certain environmental factors, such as stress or toxins, during prenatal development can lead to epigenetic changes that increase the risk of developing certain diseases later in life.

In addition to development, epigenetic regulation involves many other biological processes, including aging and disease. As we age, our DNA becomes increasingly methylated, which can result in silencing genes important for maintaining cellular function. This can contribute to age-related decline in physiological function and the development of age-related diseases, such as cancer and Alzheimer's.

Epigenetic changes have also been implicated in the developing of various diseases, including cancer. Cancer cells often have altered patterns of DNA methylation and histone modification, allowing them to grow and divide uncontrollably. In some cases, drugs that target epigenetic modifications have been developed as cancer therapies.

Overall, the function of epigenetic regulation is to control gene expression and ensure that different genes are expressed at the right time and in the right place. Environmental factors can influence epigenetic modifications and be passed down from generation to generation. They play a critical role in development, aging, and disease, and understanding epigenetic regulation has important implications for human health and disease prevention.

Real Vita ACV Keto Gummies

Many people associate elevated ketones with a diabetic medical emergency known as ketoacidosis, but nutritional ketosis associated with a ketogenic diet anddiabetic ketoacidosisare very different. The entire point of being on healthy diets like the Keto Diet is to stay away from stuff like wheat protein in order to allow the body to heal itself. Moreover, wheat protein actively prevents the body from burning fat by initiating a metabolic pathway called the neoglucogenesis. A Keto Diet can be bad for health if executed improperly.

While much of the initial rapid weight loss is water weight , it’s still a highly motivating way to start your keto journey. Often, just restricting carbs to very low levels results in ketosis. But the rest of the list below will help make sure that you’re successful. A keto diet can also help treat high blood pressure,46 may result in less acne,47 and may help control migraine.48 It may also help improve many cases of PCOS and heartburn, while also often reducing sugar cravings.

Still, the results of this study need to be interpreted carefully due to its relatively low sample size and lack of randomization of participants into KD or control group . However, the main mechanism of influence of the KD on the human body is its impact on metabolic reorganization .

After transporting the KB to extrahepatic cells, they can be used as an energy substrate (acetyl-CoA) in the production of ATP through the oxidative phosphorylation pathway in the citric acid cycle . By following the keto diet, about 60 to 80 percent of your daily calories will come from fat. Ketogenic Diet These are low-carb diets -- the basic idea is to get most of your calories from protein and fat.

Read: Factors We Considered Before Choosing The Best Real Vita ACV Keto Gummies

The keto diet is actually known to benefit risk factors for cardiovascular disease. In a study of 83 obese individuals, a long-term keto diet significantly reduced triglycerides and LDL cholesterol and increased HDL cholesterol. In other words, the keto diet improved all measured cardiovascular disease risk factors. Don't be surprised if you've been following a keto diet and someone tells you your breath smells a little fruity or "off." This is actually a sign that you are in ketosis.

Unfortunately, keto diets are probably more prone than many others to end with weight regain because they can be hard to stick to in the long run, Carson said. And being in ketosis for more than a few weeks might not be best for overall health, she said. That's true of many diet studies, the researchers noted, so study results likely look rosier than weight loss in the real world. For reasons not entirely understood even today, fueling the body on primarily ketones reduces seizures.

I know that Acetyl-CoA is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism. Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production. Coenzyme A consists of a β-mercaptoethylamine group linked to the vitamin pantothenic acid through an amide linkage and 3’-phosphorylated ADP. The acetyl group of Acetyl-CoA is linked to the sulfhydryl substituent of the β-mercaptoethylamine group.

NAD+ (Nicotinamide Adenine Dinucleotide)  The Essential Molecule for Life, Aging, and Health

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme that plays a crucial role in several vital biological processes. Often referred to as the "molecular currency of life," NAD+ is indispensable for energy production, DNA repair, and maintaining cellular health. Its importance spans from fundamental cell metabolism to its implications in aging and age-related diseases. In this article, we will explore the role of NAD+ in the human body, its biochemical pathways, its relationship with aging, and the potential therapeutic benefits of boosting NAD+ levels.

1. What is NAD+?

NAD+ is a coenzyme found in all living cells, composed of two nucleotides linked by their phosphate groups: one nucleotide contains adenine, and the other contains nicotinamide. It is involved in redox reactions, carrying electrons from one reaction to another. The molecule exists in two forms: NAD+ (oxidized) and NADH (reduced). These two forms are crucial in energy production, specifically in cellular respiration.

The primary role of NAD+ is to facilitate the transfer of electrons in metabolic processes, including glycolysis, the citric acid cycle, and oxidative phosphorylation. These processes generate ATP, the energy currency of the cell. NAD+ is also essential for the proper function of several enzymes, including sirtuins and poly(ADP-ribose) polymerases (PARPs), which are involved in DNA repair and maintaining cellular health.

2. The Role of NAD+ in Energy Metabolism

At the core of NAD+'s function is its involvement in energy metabolism. Through redox reactions, NAD+ helps transfer electrons during the breakdown of glucose, fats, and proteins into ATP, which cells use for energy. The NAD+/NADH cycle is central to this process.

Glycolysis: The breakdown of glucose to pyruvate in the cytoplasm of the cell produces NADH. This NADH is then used in the mitochondria to produce ATP through oxidative phosphorylation.

Citric Acid Cycle (Krebs Cycle): In the mitochondria, NAD+ helps in the oxidation of acetyl-CoA into carbon dioxide and high-energy electrons. This process generates NADH, which later donates electrons to the electron transport chain for ATP production.

Oxidative Phosphorylation: NADH generated in glycolysis and the citric acid cycle enters the electron transport chain in mitochondria. Here, NADH is oxidized back to NAD+, and the electrons it carries are used to generate a proton gradient across the mitochondrial membrane, driving ATP production.

Thus, NAD+ is fundamental to the energy-producing machinery of the cell. Without adequate levels of NAD+, cellular energy production would halt, leading to cell death and, ultimately, organismal dysfunction.

3. NAD+ in DNA Repair and Maintenance

In addition to its role in energy metabolism, NAD+ is crucial for maintaining the integrity of the genome. It acts as a substrate for a class of enzymes called sirtuins, which regulate a wide range of cellular processes, including DNA repair, inflammation, and stress resistance. Sirtuins require NAD+ to function properly, and they use it to remove acetyl groups from proteins, a process known as deacetylation.

DNA repair is one of the critical functions of sirtuins. As cells undergo stress and damage from environmental factors like UV radiation or oxidative stress, their DNA accumulates mutations and breaks. NAD+-dependent sirtuins repair these DNA lesions, ensuring cellular longevity and proper function.

Another important family of enzymes that rely on NAD+ are poly(ADP-ribose) polymerases (PARPs). PARPs are involved in detecting DNA damage and triggering repair processes. These enzymes consume large amounts of NAD+ to add ADP-ribose units to target proteins, which is a signal to initiate the repair of DNA breaks.

The depletion of NAD+ impairs DNA repair mechanisms, leading to the accumulation of genetic mutations and cellular aging. This underscores the importance of maintaining sufficient NAD+ levels to preserve cellular health and prevent diseases like cancer.

4. NAD+ and Aging

As we age, the levels of NAD+ in our cells naturally decline. This decrease is associated with several age-related conditions, including metabolic disorders, cardiovascular diseases, neurodegenerative diseases, and a general decline in cellular function. The reduced availability of NAD+ impairs energy metabolism, DNA repair, and cellular maintenance, leading to the aging process.

The decline in NAD+ levels is partly due to the increased activity of enzymes that consume NAD+, such as PARPs and sirtuins. As these enzymes work overtime to repair DNA and respond to cellular stress, they deplete NAD+ stores, creating a vicious cycle of declining NAD+ and increased cellular damage.

Researchers have found that restoring NAD+ levels in aged organisms can have remarkable health benefits, including improved energy metabolism, enhanced DNA repair, and the reversal of certain age-related diseases.

5. NAD+ and Age-Related Diseases

Many age-related diseases, including Alzheimer's disease, Parkinson's disease, diabetes, and cardiovascular diseases, are associated with a decline in NAD+ levels. As NAD+ is essential for mitochondrial function and cellular repair, a reduction in NAD+ impairs these processes, leading to disease progression.

Neurodegenerative Diseases: In Alzheimer's and Parkinson's diseases, mitochondrial dysfunction and DNA damage contribute to the death of neurons. NAD+ depletion has been shown to exacerbate these conditions by impairing mitochondrial function and DNA repair. Restoring NAD+ levels through supplementation or other means has been suggested as a potential therapeutic strategy for slowing or halting neurodegeneration.

Metabolic Diseases: NAD+ is also crucial for the regulation of metabolism, especially in the liver, muscles, and adipose tissue. Low NAD+ levels have been linked to insulin resistance and metabolic disorders such as type 2 diabetes. Increasing NAD+ levels can improve insulin sensitivity and glucose metabolism.

Cardiovascular Diseases: NAD+ deficiency is associated with endothelial dysfunction, oxidative stress, and inflammation, all of which contribute to cardiovascular diseases. Research suggests that boosting NAD+ levels can improve vascular function, reduce inflammation, and potentially prevent heart disease.

6. Strategies to Boost NAD+ Levels

Given the importance of NAD+ in health and aging, researchers have explored various strategies to boost NAD+ levels in the body. These strategies include:

NAD+ Precursors: The most direct way to increase NAD+ levels is by supplementing with precursors that are converted into NAD+ in the body. The most commonly studied precursors include nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). Both NR and NMN are converted into NAD+ by cellular enzymes, and studies have shown that supplementation with these molecules can increase NAD+ levels and improve health outcomes in aging animals and humans.

Exercise: Physical activity has been shown to increase NAD+ levels by enhancing the activity of enzymes involved in NAD+ biosynthesis, such as NAMPT (nicotinamide phosphoribosyltransferase). Regular exercise, especially endurance training, can naturally raise NAD+ levels and promote mitochondrial health.

Caloric Restriction and Intermittent Fasting: Both caloric restriction and intermittent fasting have been shown to increase NAD+ levels by activating sirtuins and other pathways that enhance NAD+ synthesis. These dietary interventions are thought to mimic the beneficial effects of low caloric intake and contribute to longevity.

NAD+ Boosting Supplements: Several supplements claim to increase NAD+ levels, including NR and NMN. Although clinical evidence is still emerging, early studies show promise for these supplements in improving mitochondrial function, reducing inflammation, and promoting healthy aging.

7. Conclusion

NAD+ is a critical molecule for life, playing an essential role in energy metabolism, DNA repair, and cellular maintenance. Its decline with age is linked to numerous age-related diseases and a general decline in health. However, emerging research suggests that boosting NAD+ levels through supplementation, exercise, and dietary interventions may offer promising therapeutic avenues for preventing or reversing age-related conditions.

As our understanding of NAD+ grows, it is becoming increasingly clear that this molecule is not just a bystander in cellular function but a key player in maintaining health and longevity. While more research is needed to fully understand the potential of NAD+ therapies, it is clear that this "molecular currency" is far more than a basic building block of life—it is a vital tool for ensuring the continued function of our cells and organs as we age.
