Explanation: 

Detailed explanation-1: -It stores energy, insulates heat, and increases buoyancy. Storing EnergyEnergy is stored in the thick, oily layer of blubber. The energy stored in blubber includes both proteins (mostly collagen) and fats (mostly lipids).

Detailed explanation-2: -Fats are used as a high density energy storage in animals and in plants (seeds). It may also be used in animals for insulation. Phospholipids are like fats but they have two fatty acids and a phosphate group joined to glycerol.

Detailed explanation-3: -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.
