Triacylglycerols are composed of

a) a glycerol backbone.

b) three fatty acids

c) amide linkages between the fatty acids and the glycerol.

d) A and B above.

e) A, B, and C above.

d) A and B above.

Explanation:

Triacylglycerols are the simplest form of lipids comprised of fatty acids. Triacylglycerols are also called as fats or neutral fats. Each molecule of triacylglycerol is composed of three fatty acids bonded to the single glycerol molecule.

Each of the three fatty acids of triacylglycerol is bonded to glycerol in an ester linkage. The main function of triacylglycerols is to serve as energy storage form and provide insulation to eukaryotic cells.
