Why are triacylglycerol’s used in the human body for energy storage?

A) They are highly hydrated, and therefore can store lots of energy.

B) They always have short fatty acid chains, for easy access by metabolic enzymes.

C) The carbon atoms of the fatty acid chains are highly reduced, and therefore yield

more energy upon oxidation.
