The complete hydrolysis of a molecule of a phospholipid, such as lecithin, will yield glycerol, two fatty acids, phosphoric acid, and a

A. Sphingosine base
B. Steroid nucleus
C. Nitrogenous base like choline
✓
D. Isoprene unit

📝 Explanation

A phospholipid is a substituted triglyceride. Lecithin (phosphatidylcholine) consists of glycerol esterified to two fatty acids and a phosphate group, which is in turn esterified to the nitrogenous alcohol choline. Complete hydrolysis breaks all these ester bonds.
