Substrati enzimatici
I substrati enzimatici sono molecole su cui agiscono gli enzimi per catalizzare reazioni chimiche. Il substrato si lega al sito attivo dell'enzima, dove subisce una trasformazione specifica per formare il prodotto della reazione. I substrati enzimatici sono strumenti essenziali nella ricerca per studiare la cinetica enzimatica, la specificità e il meccanismo d'azione. Sono utilizzati anche in saggi diagnostici e studi biochimici. Presso CymitQuimica, offriamo una selezione diversificata di substrati enzimatici di alta qualità per supportare le vostre ricerche in enzimologia e biochimica.
