Detailed explanation-1: -Because lipids include a high percentage of C-H bonds, which store chemical potential energy more effectively than other molecules, fats have a substantially higher energy density than carbohydrates. Hence, fats contain more energy per gram than carbohydrates.

Detailed explanation-2: -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-3: -Therefore, when the greater number of electrons around the carbon atoms in fatty acids are transferred to oxygen (when the fatty acids are oxidized), more energy is released than when the same process happens to carbohydrates.

Detailed explanation-4: -However, both fats and oils are called triglycerides because they have three fatty acid chains attached to a glycerol molecule, as shown in Figure 3. The carbon-hydrogen bonds (abbreviated C-H) found in the long tails of fatty acids are high-energy bonds.
