L-Carnosine CAS #305-84-0
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.

Copper acetate peptide, also known as blue copper peptide. Copper peptide, also known as tripeptide in Chinese; Glycyl-L-histomyl-L-lysine. Peptide is a small molecule protein composed of amino acids, which are more easily absorbed by the skin and have more significant effects. It was first isolated from human plasma in 1973 and was discovered to have wound repair function in 1985. In 1999, researchers believed that copper peptide and its copper repair products can serve as activators of tissue remodeling, and it is also a signaling peptide, Promote the degradation of a large amount of collagen aggregates outside scars, the synthesis of normal collagen in the skin, the generation of elastin, proteoglycans, and glucosamine glycans, the growth rate and migration of different cell types, anti-inflammatory, and antioxidant responses.
