BIOMOLECULES AND ENZYMES

Detailed explanation-1: -However, fats do have important functions. Many vitamins are fat soluble, and fats serve as a long-term storage form of fatty acids: a source of energy. They also provide insulation for the body.

Detailed explanation-2: -In animals the most evident function of fats is that of a food reserve to supply energy (through subsequent enzymatic oxidation-that is, combination with oxygen catalyzed by enzymes). The storage of fat in vegetable seeds can be explained similarly on the basis that it is a food reserve for the embryo.

Detailed explanation-3: -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.

Detailed explanation-4: -Adipose (fat) cells are specialized for the storage of energy in the form of triglycerides, but research in the last few decades has shown that fat cells also play a critical role in sensing and responding to changes in systemic energy balance.

Detailed explanation-5: -Animals are equipped with fat not only for energy storage, but also for regulation of body temperature and as a source of many hormones. It is reasonable that animals eat and store fat based on physiological demands.
