Enzymatic synthesis and antioxidant property of gelatin-catechin conjugates

摘要

Gelatin-catechin conjugate was synthesized by the laccase-catalyzed oxidation of catechin in the presence of gelatin.The conjugate had a good scavenging activity against superoxide anion radicals.Moreover,the conjugate showed an amplified inhibition effect on human low density lipoprotein oxidation initiated by 2,2'-azobis(2-amidinopropane)dihydrochloride as a radical generator.
