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.
EC 3.4.21.14, previously classified, now redirects to EC 3.4.21.67, identifying endopeptidase So. This serine endopeptidase is integral in the hydrolysis of peptide bonds, a critical function in biological systems. Its applications extend across research and development in the pharmaceutical and biotechnological industries.
Hydrolyzed keratin is originated from wool and is a light yellow to brownish-yellow clear fluid with a particular smell. It needs to undertake unique organic treatment to come to be brief peptides prior to it can be naturally used. Treated keratin is an acknowledged prospective resource of high-quality healthy protein with high nutritional value and secure quality.
It is a keratin hydrolysate derived from acid, enzyme and other hydrolysis methods, and has been used in feed and food industry, pharmacy, fertilizer, pesticide, environmental protection, leather industry, cosmetics and many other fields. Specifically, the material can be blended with polyamide 6 to prepare nanofibers for adsorbing chromium (VI). In addition, the compound can be used as an effective ingredient in the manufacture of shampoo, shower gel and shower gel. In addition, the chemical can be used as an effective ingredient in the production of deodorization compositions. In addition, the substance has been proven to be useful as a hair styling agent.

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.
