Lipids generally refer to lipids, which are one of the important nutrients needed by the human body, provide energy and essential fatty acids needed by the human body, and are components of human cells and tissues.

Lipids include:

1, fat function: a good energy storage substance in cells; Reduce heat loss and keep body temperature constant; Reduce the friction between internal organs and have the function of buffering external pressure.

2. Phospholipid function: It is an important part of cell membrane, mitochondrial membrane, chloroplast membrane and other structures-all cells contain phospholipids.

Extended data esters produced by dehydration and condensation of fatty acids and alcohols and their derivatives are collectively called lipids, including fats, waxes, steroids, fat-soluble vitamins (such as vitamins A, D, E, K), monoglycerides, diglycerides, phospholipids, etc.

The main physiological functions of lipids include energy storage, cell membrane formation and membrane information transmission. Today, lipids have been used in beauty and food industries, as well as nanotechnology.
