Quizplus · Accepted Answer

(1) FALSE - Bile acids are synthesized from cholesterol but they are not oxidation products of cholesterol.
(2) TRUE - Glycerophospholipids have a glycerol backbone and have one or more phosphate groups esterified to one of the hydroxyls of the glycerol, while fats have three fatty acid molecules esterified to the three hydroxyl groups of the glycerol.
(3) FALSE - Stearic acid and linolenic acid are not the two essential fatty acids. The two essential fatty acids are linoleic acid and alpha-linolenic acid.
