Substrats d'enzymes
Les substrats enzymatiques sont des molécules sur lesquelles les enzymes agissent pour catalyser des réactions chimiques. Le substrat se lie au site actif de l'enzyme, où il subit une transformation spécifique pour former le produit de la réaction. Les substrats enzymatiques sont des outils essentiels dans la recherche pour étudier la cinétique enzymatique, la spécificité et le mécanisme d'action. Ils sont également utilisés dans les essais diagnostiques et les études biochimiques. Chez CymitQuimica, nous offrons une sélection diversifiée de substrats enzymatiques de haute qualité pour soutenir vos recherches en enzymologie et biochimie.
