Question

multiple choice: which of the following is/are needed to form a triglyceride molecule? a 3 glycerol molecules b 3 fatty acid molecules c 3 fatty acid molecules and 1 glycerol molecule d 1 glycerol molecule e 3 glycerol molecules and 3 fatty acid molecules

Explanation:

Triglycerides are formed through a condensation reaction. One glycerol molecule reacts with three fatty acid molecules. Glycerol has three hydroxyl groups ($-OH$), and each fatty acid has a carboxyl group ($-COOH$). The hydroxyl group of glycerol reacts with the carboxyl group of fatty acid, losing a water molecule ($H_2O$) in each reaction. So, the components needed are 3 fatty acid molecules and 1 glycerol molecule.

Answer:

C. 3 fatty acid molecules and 1 glycerol molecule
