Question

Quizplus · Accepted Answer

Ceramide does not contain glycerol in its structure, unlike phospholipids and plasmalogens, which do. Phospholipases target the ester linkages in glycerophospholipids, releasing glycerol as a product. Since no glycerol is released, the lipid is likely not a glycerophospholipid, making ceramide the correct answer.
