Do lipids store energy?

Sugars are another source of energy, but not a good storage of energy. The carbon in Sugar makes less energy when it is oxidized. #H-C-OH# This is a typical carbon in a sugar. It has a 0(zero) oxidation state. When it gets oxidized to #CO_2#, it goes to a +4 oxidation state. This is 4 electrons changing hands. read more

Thats because lipids contain chains of fatty acids and metabolising fatty acids gives out a lot of energy. ATP is the energy currency here. A fatty acid chain is broken down by removing two carbons as acetyl-CoA successively at each step in a process known as beta oxidation. read more

While the lipids are slowly releasing energy that is being stored for the body, carbohydrates have already exhausted all of their energy stores, and they will not be able to help the body stay in a satisfied state the way that lipids do. read more
