D-Cisteína

Descripción:

D-Cisteína es un aminoácido que sirve como bloque de construcción para proteínas y se caracteriza por su grupo tiol (-SH), que le confiere propiedades químicas únicas. Es el D-enantiómero de la cisteína, lo que significa que tiene una disposición espacial específica de átomos que lo distingue de su forma L, que se encuentra más comúnmente en la naturaleza. D-Cisteína es menos prevalente en sistemas biológicos, pero puede ser sintetizado y utilizado en diversas aplicaciones bioquímicas. Juega un papel en reacciones redox debido a la reactividad de su grupo tiol, lo que lo hace importante en la formación de enlaces disulfuro y en los mecanismos de defensa antioxidante celular. D-Cisteína es soluble en agua y exhibe una naturaleza ligeramente ácida, con un valor de pKa que le permite existir en formas protonadas y desprotonadas dependiendo del pH del entorno. Su número CAS, 921-01-7, es un identificador único que facilita su reconocimiento en bases de datos químicas y literatura. En general, D-Cisteína es significativo en investigaciones y aplicaciones industriales, particularmente en los campos de la bioquímica y la farmacéutica.

D-Cysteine

CAS: 921-01-7

D-Cysteine is the L-cysteine stereoisomer. It has been shown to inhibit the response of nicotinic acetylcholine receptors and toll-like receptor 4, which are proteins that play a role in inflammation. D-Cysteine also inhibits the production of nitric oxide by inhibiting NADPH oxidase. This inhibition leads to decreased inflammation, as well as decreased oxidation of proteins and DNA. D-Cysteine has been shown to be a specific inhibitor of wild type strains of Escherichia coli, but not mutant strains with defects in iron homeostasis. The enzyme activity for d-cysteine is also inhibited by l-cysteine, which may result in drug interactions. D-Cysteine can be found naturally in foods such as garlic, onions, broccoli, and cauliflower.
