Biosynthesis of cholesterol pdf

WebBiosynthesis of cholesterol generally takes place in the endoplasmic reticulum of hepatic cells and begins with acetyl- CoA, which is mainly derived from an oxidation reaction in the mitochondria. However, acetyl-CoA can also be derived from the cytoplasmic oxidation of ethanol by acetyl-CoA synthetase. Webcholesterol biosynthesis causes a disorder, which results in accumulation of specifi c cholesterol precursors [34]. In the postsqualene cholesterol biosynthesis pathway, cyclization of squalene-2,3-epoxide gives the fi rst sterol, lanosterol, which is followed by multistep transformations, leading to the ultimate product cholesterol (Scheme 1).
