Phospholipid

- Feb 17, 2021-

Phospholipid, also known as phospholipid or phospholipid, is a lipid containing phosphoric acid and is a complex lipid. Phospholipids are a type of lipids containing phosphoric acid. The body mainly contains two types of phospholipids. Phospholipids composed of glycerol are called phosphoglycerides; phospholipids composed of sphingosine are called sphingolipids.

Phospholipids are important amphiphilic substances. They are important components of biological membranes, emulsifiers and surfactants (surfactants are substances that can reduce the surface tension of liquids, usually water, and diffuse along the water surface), phospholipids ( Phospholipid) is an important part of biological membranes, which is characterized by the metabolism of phospholipids containing fatty acids and phosphoric acid after hydrolysis.

Phospholipid metabolism. Phospholipids can be hydrolyzed into glycerol, fatty acids, phosphoric acid and various amino alcohols (such as choline, ethanolamine, serine, etc.) by various phospholipases in the body. Glycerol can be converted into dihydroxyacetone phosphate to participate in sugar metabolism. Fatty acids are decomposed by β-oxidation. Phosphoric acid is an indispensable substance in the metabolism of various substances in the body. Various amino alcohols can participate in the re-synthesis of phospholipids in the body, and choline can also be converted into other substances by transmethylation. During the synthesis of phospholipids, ethanolamine or choline and ATP produce China Phosphorylethanolamine or phosphorylcholine under the action of kinases, and then react with ctp to convert into citicoline or citicoline. Citicoline or Citicoline can synthesize the corresponding phospholipids with the already formed diglycerides (see the formation of triglycerides).  

The function of phospholipids

Phospholipids are lipid compounds containing phospholipid roots and are the basic substance of life. The cell membrane is composed of about 40% protein and about 50% lipid (mainly phospholipids). It is composed of lecithin, inositol phospholipid, cephalin and so on. These phospholipids have corresponding functions on various parts and organs of the human body.

Phospholipids are contained in all cells of the human body, which are the basic substances for maintaining life activities. Phospholipids can play an important role in activating cells, maintaining metabolism, basal metabolism and balanced secretion of hormones, and enhancing the body's immunity and regeneration. Generally speaking, the basic functions of phospholipids are: strengthening brain power, stabilizing nerves, balancing endocrine, improving immunity and regeneration, detoxification and diuresis, cleansing blood, strengthening skin, maintaining youthfulness, and continuing aging.
