Detailed explanation-1: -Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids.

Detailed explanation-2: -Fats (lipids) Fats are the primary long-term energy storage molecules of the body. 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.

Detailed explanation-3: -The main type of fat we consume, triglycerides are especially suited for energy storage because they pack more than twice as much energy as carbohydrates or proteins. Once triglycerides have been broken down during digestion, they are shipped out to cells through the bloodstream.

Detailed explanation-4: -They are a concentrated energy source, providing more energy per gram than the carbohydrates. Unlike the carbohydrates, the body is able to store lipids in the body, and they are therefore an important long term source of energy.
