Phospholipid molecules are composed of glycerol molecules, fatty acid molecules, phosphoric acid molecules and nitrogen molecules. Wherein glycerol molecules combine with fatty acids to form glycerides, and phosphoric acid molecules and nitrogen molecules combine with glycerides to form phospholipids.
Among the components of phospholipids, glycerol is one of the carbohydrates that constitute organisms, while fatty acids are the main components of fats that constitute organisms. Phosphoric acid can provide phosphorus, and nitrogen can provide nitrogen, which are essential elements in organisms.
The special property of phospholipid is that it has a hydrophobic tail and a hydrophilic head in its molecular structure. This structure enables phospholipids to interact with water molecules, thus playing an important structural role in biofilm. In cell membrane, phospholipid molecules are arranged in double layers, which constitute the basic skeleton of cell membrane and play an important role in maintaining the morphology and structure of cells.
Application of phospholipids in life;
1. food additives: phospholipids are used as emulsifiers, stabilizers and antioxidants in the food industry. They can help improve the taste and texture of food and extend the shelf life. Especially when making baked goods, dairy products and meat products, phospholipids can improve the quality of products.
2, health care products: phospholipids have many benefits to the human body, so they are often made into health care products. They help to improve memory, lower cholesterol and relieve stress. Some studies show that phospholipids can also promote brain health and prevent Alzheimer's disease.
3. Drugs: Phospholipids are also used in the manufacture of drugs. For example, they can be used as drug carriers to help drugs be better absorbed and distributed. In addition, phospholipids can also be used to make medicinal ointments and suppositories.
4. Cosmetics: Phospholipids are also widely used in cosmetics. They can be used as humectants, softeners and antioxidants to help keep skin moist and elastic. In addition, phospholipids can also be used to make cosmetics such as lipstick and mascara.
