Polyglutamic acid (y-PGA), also known as natto gum, is a high molecular peptide polymer synthesized from several glutamic acid monomers through microbial fermentation. It is rich in glutamic acid, glucose, protein and minerals. , vitamins and other biologically active substances.

Polyglutamic acid (??-PGA) is a sticky substance that was first discovered in ??Natto??. It is currently widely used in agricultural production and is called a new biostimulant. It is fully water-soluble, biodegradable, edible, and non-toxic. It is a biopolymer produced by microbial fermentation.

Carnosine was discovered together with carnitine by the Russian chemist Gurevitch. Studies in the UK, South Korea, Russia and other countries have shown that carnosine has strong antioxidant capacity and is beneficial to the human body. Carnosine has been shown to scavenge reactive oxygen species (ROS) and ??-?? unsaturated aldehydes formed during oxidative stress by excessive oxidation of fatty acids in cell membranes.

L-Carnosine is a small molecule with a left-handed structure of a natural dipeptide that is ubiquitous in nature. It is a dipeptide composed of ??-alanine and L-histidine. Carnosine has cellular antioxidant, anti-aging and various physiological health functions and medical effects. It has therapeutic effects on hypertension, heart disease, senile cataracts, ulcer healing, etc. It also has anti-tumor, immune model tests, and anti-stress effects. stimulating factors and other effects.
