A typical fat molecule is built from one glycerol bonded to:
ATwo chains
BFour chains
CSix chains
DThree chains
Answer & Solution
Correct answer: D. Three chains
1. A fat has two main components, glycerol and fatty acids.
2. Glycerol carries three hydroxyl groups, one on each of its three carbons.
3. A fatty acid attaches at each of those three carbons by an ester bond.
4. So a typical fat holds three fatty acid chains, which is why fats are also called triglycerides.
