MCAT Practice Questions | Verified Solutions With Real Quiz 2023 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. D) Polysaccharides, which would actually be a better energy storage form, would dissolve in...
