Substratos enzimáticos
Substratos enzimáticos são moléculas sobre as quais as enzimas atuam para catalisar reações químicas. O substrato liga-se ao sítio ativo da enzima, onde passa por uma transformação específica para formar o produto da reação. Os substratos enzimáticos são ferramentas essenciais na pesquisa para estudar a cinética enzimática, especificidade e mecanismo de ação. Eles também são usados em ensaios diagnósticos e estudos bioquímicos. Na CymitQuimica, oferecemos uma seleção diversificada de substratos enzimáticos de alta qualidade para apoiar suas pesquisas em enzimologia e bioquímica.
