Question

Membrane sphingolipids are synthesized in the cytosol synthesized by reacting the head group with sphingosine and then attaching a fatty acyl-CoA in an amide linkage dietary essential synthesized by first reacting palmitoyl-CoA with serine O In cholesterol biosynthesis, O the activated isoprene units are mevalonate and dimethylallyl pyrophosphate O all of the carbons originate in acetyl-CoA squalene is the first fused ring structure formed O the HMG-CoA synthase is the same enzyme found in ketone body synthesis Cholesterol is not converted to vitamin A bile acids cholesteryl ester steroid hormones

Explanation / Answer

1)-option d is correct because firstly palmitoyl CoA react with serine and 3-ketodihydrosphingosine is formed.

2)-option b is correct because in cholesterol all 27 carbon atoms derived from acetyl CoA.

3)-option a is correct because cholesterol is converted into bile acid, steroids and cholesteryl ester.
