Question

Quizplus · Accepted Answer

Glycerophospholipids, also known as phosphoglycerides, have two fatty acid chains esterified at the sn-1 and sn-2 positions of glycerol, and a phosphoric acid molecule esterified at the sn-3 position. Therefore, option B - two fatty acid and one phosphoric acid molecules, is the correct choice. Option A has only one phosphoric acid molecule, which is incorrect. Option C has three phosphoric acid molecules, which is not possible since there are only three -OH groups on glycerin. Option D has an amino alcohol molecule, which is not typically found in glycerophospholipids.
