Regulation of Blood Cholesterol Levels.

Cholesterol biosynthesis
80% of endogenous cholesterol is formed in the liver. Enzymes involved in the synthesis are partly located in the endoplasmic reticulum and partly in the cytoplasm. Acetyl CoA is the precursor. HMG CoA, mevalonate, isopentenyl pyrophosphate, squalene are some of the important intermediate compounds formed during cholesterol synthesis. Cholesterol is transported in lipoprotein complexes. Elevation of lipids in blood leads to the deposition of cholesterol on the arterial walls leading to atherosclerosis.
