Polyglutamic acid is a kind of polypeptide, which is composed of multiple glutamic acid molecules linked by peptide bonds. It is a high-molecular organic substance with hydrophilic and water-absorbing properties. It can form a large number of protonated carboxyl groups in organisms, which can attract and bind water molecules and maintain the water balance inside and outside the cells. Polyglutamic acid has good effects in moisturizing the skin, reducing pigmentation and lightening wrinkles, and is widely used in the medical and beauty industries.
Polyglutamic acid is widely used in medical and beauty industries. Specific application areas include:
1. Skin repair: Polyglutamic acid can increase the moisture content of the skin, enhance the skin barrier function, help maintain the health and elasticity of the skin, reduce fine lines and wrinkles, and promote skin repair.
2. Beauty and anti-aging: Because polyglutamic acid has multiple functions such as moisturizing and anti-oxidation, it can help the skin to resist aging and maintain luster.
3. Diabetes: Polyglutamic acid can help regulate blood sugar, increase insulin sensitivity and secretion, and has a certain auxiliary therapeutic effect on diabetic patients.
4. Cell culture: Polyglutamic acid is also widely used in cell culture, which can provide the nutrients needed by cells, maintain the stability of cell shape and function, and promote cell growth and differentiation.
