SYNTHESIS OF CHOLESTEROL AND PHOSPHOLIPID FROM ACETYL COA Biosynthesis Cholesterol occurs in every nucleated cell in the body. Although it is often thought that the majority of cholesterol synthesis occurs in the liver, studies have shown that the bulk tissues of the body account for the overwhelming majority of endogenous cholesterol production. Hepatic cholesterol synthesis in humans is thought to contribute 10–20% of the total daily synthesis rate. Since the majority of cholesterol synt

Organisms derive the majority of their energy from the Kreb's Cycle, also known as the TCA cycle. The Kreb's Cycle is an aerobic process consisting of eight definite steps. In order to enter the Kreb's Cycle pyruvate must first be converted into Acetyl-CoA by pyruvate dehydrogenase complex found in the mitochondria.

is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. The Krebs cycle is used by organisms that respire (as opposed to organisms that ferment) to generate energy, either by anaerobic respiration or aerobic respiration. In addition, the cycle provides precursors of certain amino acids, as well as the reducing agent NADH, that are used in numerous other reactions.

Energy system #3 includes slow glycolysis, Krebs cycle, and the Electron Transport Chain. The fuel source for this system is Acetyl-CoA (from glycolysis or beta oxidation), and amino acids. It is indefinite; it never stops, it can only decrease or increase the rate. This system can be improved by increasing the mitochondria in a cell.

Oxidative Decarboxylation of pyruvate: in mitochondria; pyruvate formed during glycolysis is transported from cytoplasm into mitochondrial matrix where it is decarboxylated (loses a CO2) & the acetyl group that remains is transferred to coenzyme A to form acetyl CoA; in the process, NAD+ is reduced to NADH

TJ. Coenzyme A (CoA, CoASH, or HSCoA) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle. All genomes sequenced to date encode enzymes that use coenzyme A as a substrate, and around 4% of cellular enzymes use it (or a thioester, such as acetyl-CoA) as a substrate. In humans, CoA biosynthesis requires cysteamine, pantothenate, and adenosine triphosphate (ATP).[1]
