L-Cysteine (Standard)

CAS: 52-90-4

L-Cysteine (Standard) is the standard substance of L-Cysteine, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

L-Cysteine

CAS: 52-90-4

L-Cysteine is a non-essential amino acid that is used in biochemical research and has been shown to inhibit the activity of nicotinic acetylcholine receptors. It also regulates the response of cells to toll-like receptor ligands by inhibiting the production of inflammatory mediators. L-Cysteine binds to a sequence called response element, which is found in many prokaryotic genes, and inhibits protein oxidation. L-Cysteine has an inhibitory effect on single-stranded RNA and can act as a rate constant for protein synthesis. L-Cysteine is an amino acid that contains sulfur and can be found in proteins with thiol groups. The cysteine residues in proteins are coordinated geometrically by a zinc ion (Zn2+) or iron ion (Fe3+). This coordination geometry affects the biological properties of these proteins.
