Question
Chapter 21, Problem 21.35P
Interpretation Introduction
Interpretation:
The ring of the steroid structure undergoes the most substitution in cholesterol needs to be identified.
Concept introduction:
The fat-like substance in the body is known as Cholesterol. It is formed by our body and also present in food. Though it is required for good health, large amount of cholesterol can harm our arteries and increase heart disease risk.
Various steroid hormones are synthesized from cholesterol as starting materials. The aliphatic side chain on the D ring undergoes a chain-shortening reaction and the hydroxyl group is oxidized to a
