L-(+)-Cystein

Beschreibung:

L-(+)-Cystein, mit der CAS-Nummer 52-90-4, ist eine natürlich vorkommende Aminosäure, die eine entscheidende Rolle bei der Proteinsynthese und verschiedenen Stoffwechselprozessen spielt. Sie wird als nicht essentielle Aminosäure klassifiziert, was bedeutet, dass der Körper sie aus anderen Verbindungen synthetisieren kann. Cystein enthält eine Thiolgruppe (-SH), was es zu einer schwefelhaltigen Aminosäure macht, die zu ihren einzigartigen Eigenschaften beiträgt, wie der Fähigkeit, Disulfidbrücken zu bilden, die die Proteinstrukturen stabilisieren. Diese Aminosäure ist bekannt für ihre antioxidativen Eigenschaften, da sie bei der Synthese von Glutathion helfen kann, einem wichtigen Antioxidans im Körper. L-(+)-Cystein ist typischerweise in eiweißreichen Lebensmitteln zu finden und ist auch als Nahrungsergänzungsmittel erhältlich. Es ist in Wasser löslich und hat eine leicht saure Natur, mit einem pKa-Wert, der seine Fähigkeit widerspiegelt, Protonen abzugeben. Neben seiner biologischen Bedeutung wird Cystein in verschiedenen industriellen Anwendungen eingesetzt, einschließlich der Herstellung von Arzneimitteln und Kosmetika, aufgrund seiner funktionalen Eigenschaften.

L-Cysteine - non-animal origin

CAS: 52-90-4

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).

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.
