Peptides
Les peptides sont des chaînes courtes d'acides aminés liées par des liaisons peptidiques, jouant un rôle essentiel en tant que molécules biologiques dans divers processus cellulaires. Ils fonctionnent comme hormones, neurotransmetteurs et molécules de signalisation, et sont largement utilisés dans les applications thérapeutiques et diagnostiques. Les peptides sont également cruciaux dans la recherche pour étudier les interactions protéiques, les activités enzymatiques et les voies de signalisation cellulaire. Chez CymitQuimica, nous proposons une large sélection de peptides de haute qualité pour soutenir vos besoins en recherche et développement en biotechnologie et en pharmacie.

CAS :Homoglutathione is a glutathione analog that contains an extra b-alanine residue. Homoglutathione has been shown to be a potent inhibitor of fatty acid synthesis. It inhibits the activity of the enzyme, acetyl-CoA carboxylase, which catalyzes the conversion of acetyl-CoA to malonyl-CoA. Homoglutathione also binds to and inhibits cytoplasmic proteins, such as glutamine synthetase and glutamate synthase. The binding of homoglutathione to these proteins prevents the formation of the active site by preventing the hydrogen bonding between amino acid residues. This process is important in energy metabolism because it regulates the production of ATP from ADP and phosphate.Formule :C11H19N3O6SDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :321.35 g/molDBCO-dPEG®12-Meso-TP-IR775
