Fatty acids of cholesterol are mainly:
Correct Answer: Palmitic acid
Description: D i.e. Palmitic acid; E i.e. Stearic acidBoth cholesterol and ketone bodies are synthesize from (3) beta hydroxyl (3) beta methyl glutary CoA (ie HMG CoA). So enzymes, thiolase & HMG CoA synthase involved in conversion of acetyl CoA to HMG CoA are common to synthesis of cholesterol and ketone bodies bothQ. However, cytoplasmic HMG CoA synthase is involved in cholesterol synthesis, whereas mitochondrial HMG CoA synthase is involved in Ketone body synthesis.Cholesterol synthesis is controlled by regulation of HMG COA reductase, which is a rate limiting enzymeQ.Cholesterol, the major sterol in animal tissue has steroid nucleusQ. Of the cholesterol absorbed, 80-90% is esterified with long chain fatty acids (mostly saturated) such as palmitic and steric acidsQ. Whereas, substitution of saturated FAs by poly unsaturated FAs in diet has beneficial effects and lowers cholesterol.
