CAS 52-90-4
:L-(+)-Cysteine
Description:
L-(+)-Cysteine, with the CAS number 52-90-4, is a naturally occurring amino acid that plays a crucial role in protein synthesis and various metabolic processes. It is classified as a non-essential amino acid, meaning that the body can synthesize it from other compounds. Cysteine contains a thiol (-SH) group, which makes it a sulfur-containing amino acid, contributing to its unique properties, such as the ability to form disulfide bonds that stabilize protein structures. This amino acid is known for its antioxidant properties, as it can help in the synthesis of glutathione, a vital antioxidant in the body. L-(+)-Cysteine is typically found in high-protein foods and is also available as a dietary supplement. It is soluble in water and has a slightly acidic nature, with a pKa value that reflects its ability to donate protons. In addition to its biological significance, cysteine is utilized in various industrial applications, including the production of pharmaceuticals and cosmetics, due to its functional properties.

CAS:<p>L-Cysteine is a non-animal derived amino acid that has been shown to help maintain normal iron levels in the body. It also helps reduce oxidative injury and inflammation. L-Cysteine is made naturally by the human body, but can be found in some foods as well. L-Cysteine has been shown to help regulate protein oxidation and injury responses in humans. L-Cysteine plays a role in the immune system by binding to Toll-like receptors, which are proteins on cells that are involved with inflammation and immunity. L-Cysteine also plays a role in the immune system by stimulating antibody production, which is important for fighting infection. Cysteine is an amino acid involved with many biochemical reactions, including synthesis of proteins and DNA molecules. Cysteine also regulates gene expression through response elements that are found in the promoter regions of genes. The rate constant for cysteine is 0.00001s^(-1).</p>Formula:C3H7NO2SColor and Shape:White PowderMolecular weight:121.16 g/molL-Cysteine
CAS:<p>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.</p>Formula:C3H7NO2SColor and Shape:White PowderMolecular weight:121.16 g/molL-Cysteine extrapure CHR, 99%
