L-Cysteine, CAS # 52-90-4, is an essential sulfur-containing amino acid related to cystine. It plays an important role in protein synthesis. It is a precursor to the glutathione antioxidant system and iron-sulfur clusters.

This Thermo Scientific Chemicals brand product was originally part of the Acros Organics product portfolio. Some documentation and label information may refer to the legacy brand. The original Acros Organics product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

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
