Cholesterol and Triglyceride Metabolism
De Novo Cholesterol Biosynthesis
Liver synthesizes 2/3 of cholesterol made by the body. The rate limiting enzyme is 3-hydroxyl 3-methyl glutaryl (HMG)-CoA reductase.
Bile acids are synthesized from cholesterol in the liver, released into the intestine and reabsorbed in the jejunum and ileum
Classification of hyperlipoproteinemia and drug treatment
Type lipoprotein Ch TG AS risk drug treatment
elevated
I CM + +++ none
IIa LDL ++ high HMG-CoA reductase inhibitors
IIb LDL+VLDL +++ ++ high fibrates, HMG-CoARI
III IDL ++ ++ moderate fibrates,
IV VLDL + ++ moderate fibrates,
V CM+VLDL + ++ none
