L-Cysteine hydrochloride anhydrous USES

1. Antioxidant effect: Cysteine hydrochloride, as a precursor of glutathione, participates in the intracellular antioxidant defense system. Glutathione is an important antioxidant that helps neutralize free radicals, maintain cell health and fight oxidative stress.

2, REDOX reaction: The sulfur group of cysteine hydrochloride can carry out REDOX reaction and help regulate the REDOX balance in cells. It is essential for many biological processes such as protein synthesis, DNA repair, and cell signaling.

3, maintain protein structure: cysteine hydrochloride will affect protein synthesis, and its sulfur group can form disulfide bonds, which play an important role in the stability and shape of proteins.

4, detoxification: cysteine hydrochloride can chemically react with some toxic substances to promote its detoxification and discharge. During detoxification, cysteine can bind to toxic substances such as heavy metal ions, reducing their damage to body tissues.
