    Nutritional Supplement Amino Acid 2-Amino-3-Mercaptopropionic Acid CAS 3374-22-9 Dl-Cysteine

    What  is Dl-Cysteine/2-Amino-3-Mercaptopropionic Acid?

    DL-Cysteine is a non-essential amino acid, meaning it can be synthesized by the human body. It is composed of both D-cysteine and L-cysteine molecules. DL-Cysteine is commonly found in various protein-rich foods such as meat, poultry, eggs, and dairy products.

    DL-Cysteine serves several crucial functions in the body. It is a precursor to the antioxidant glutathione, which plays a vital role in detoxification processes and protecting cells from oxidative damage. Additionally, DL-Cysteine is involved in the synthesis of proteins, peptides, and other sulfur-containing compounds essential for various physiological processes. Moreover, it plays a role in maintaining the structure of proteins and enzymes, contributing to their stability and functionality. DL-Cysteine also participates in the regulation of the immune system and is important for skin and hair health.
