Question

question 19 (2.5 points)
a triglyceride molecule is made up of
one glycerol and two fatty acids
two fatty acids and two glycerols
one fatty acid and three glycerols
one glycerol and three fatty acids
one glycerol and two fatty acids

Explanation:

Triglycerides are lipids. They are formed by a condensation reaction between glycerol (a three - carbon alcohol) and fatty acids. The chemical formula of a triglyceride shows that one glycerol molecule reacts with three fatty acid molecules. Each - OH group on the glycerol reacts with the - COOH group of a fatty acid, forming an ester bond and releasing a water molecule for each bond formed.

Answer:

one glycerol and three fatty acids
