CAS 52-90-4
:L-(+)-Cystéine
Description :
L-(+)-Cystéine, avec le numéro CAS 52-90-4, est un acide aminé qui se trouve naturellement et joue un rôle crucial dans la synthèse des protéines et divers processus métaboliques. Il est classé comme un acide aminé non essentiel, ce qui signifie que le corps peut le synthétiser à partir d'autres composés. La cystéine contient un groupe thiol (-SH), ce qui en fait un acide aminé contenant du soufre, contribuant à ses propriétés uniques, telles que la capacité de former des liaisons disulfure qui stabilisent les structures protéiques. Cet acide aminé est connu pour ses propriétés antioxydantes, car il peut aider à la synthèse du glutathion, un antioxydant vital dans le corps. L-(+)-Cystéine se trouve généralement dans des aliments riches en protéines et est également disponible sous forme de complément alimentaire. Il est soluble dans l'eau et a une nature légèrement acide, avec une valeur de pKa qui reflète sa capacité à donner des protons. En plus de son importance biologique, la cystéine est utilisée dans diverses applications industrielles, y compris la production de produits pharmaceutiques et cosmétiques, en raison de ses propriétés fonctionnelles.

CAS :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).Formule :C3H7NO2SCouleur et forme :White PowderMasse moléculaire :121.16 g/molL-Cysteine
CAS :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.Formule :C3H7NO2SCouleur et forme :White PowderMasse moléculaire :121.16 g/molL-Cysteine extrapure CHR, 99%
