General Description

  • L-Cysteine is an essential amino acid and is one of the building blocks required for the synthesis of proteins
  • This compound participates in the glutathione antioxidant system and iron-sulfur clusters

Applications

  • It plays a role in the production of flavors such as meat flavor obtained by reacting with sugars
  • This compound is also applied to the cleavage of disulfide bonds in keratin, the main protein in nails, skin, and hair
  • In chemical research, it is used as a crucial raw material in the manufacture of N-acetyl-L-cysteine, S-carboxymethyl-L-cysteine, and L-cysteine base
  • L-Cysteine is a component of the antioxidant glutathione and has been shown to be involved in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin
  • In vitro studies demonstrated that this compound can neutralize the activity of acetaminophen. In addition, due to its antioxidant activity this compound can protect the nervous system.
  • This compound can also bind to several metal cofactors in enzymes
