a.   The four fused rings form the steroid nucleus.
b.   The cholesterol molecule contains a hydroxyl group (—OH) on the first ring, one double bond in the second ring, methyl groups (—CH3) at carbons 10 and 13, and a branched carbon chain.
c.   The hydroxyl group determines the sterol classification.


Cholesterol is not soluble in water; it is classified with the lipid family.
