L-(+)-Cisteina

Descrizione:
L-(+)-Cisteina, con il numero CAS 52-90-4, è un aminoacido che si trova naturalmente e svolge un ruolo cruciale nella sintesi delle proteine e in vari processi metabolici. È classificato come un aminoacido non essenziale, il che significa che il corpo può sintetizzarlo a partire da altri composti. La cisteina contiene un gruppo tiolico (-SH), che la rende un aminoacido contenente zolfo, contribuendo alle sue proprietà uniche, come la capacità di formare legami disolfuro che stabilizzano le strutture proteiche. Questo aminoacido è noto per le sue proprietà antiossidanti, poiché può aiutare nella sintesi del glutatione, un antiossidante vitale nel corpo. L-(+)-Cisteina si trova tipicamente in alimenti ad alto contenuto proteico ed è disponibile anche come integratore alimentare. È solubile in acqua e ha una natura leggermente acida, con un valore di pKa che riflette la sua capacità di donare protoni. Oltre alla sua importanza biologica, la cisteina è utilizzata in varie applicazioni industriali, inclusa la produzione di prodotti farmaceutici e cosmetici, grazie alle sue proprietà funzionali.

  • L-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>

  • L-Cysteine - non-animal origin

    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>
