Detailed explanation-1: -Because one triglyceride molecule yields three fatty acid molecules with as much as 16 or more carbons in each one, fat molecules yield more energy than carbohydrates and are an important source of energy for the human body.
Detailed explanation-2: - Lipids have more carbon-hydrogen bonds than carbohydrates, thus contain more energy per gram than carbohydrates or proteins, which explains why fats have a greater caloric value.
Detailed explanation-3: -Fats (lipids) Fats are very compact and light weight, so they are an efficient way to store excess energy. A fat is made up of a glycerol, which is attached to 1 to 3 fatty acid chains. Most of the energy from fats comes from the many carbon bonds in these long, fatty acid chains.
Detailed explanation-4: -The carbon-hydrogen bonds (abbreviated C-H) found in the long tails of fatty acids are high-energy bonds. Thus, triglycerides make excellent storage forms of energy because they pack many high-energy C-H bonds into a compact structure of three tightly packed fatty acid tails.
