Dihydroquercetin polymerization using laccase immobilized into an ionic liquid

It was shown that the laccase (LC) included into hydrophobic ionic liquid (IL) can be reused for the biotransformation of dihydroquercetin (DHQ). The physicochemical characteristics of DHQ oligomers synthesized using LC/IL did not differ from the characteristics of the oligomers obtained with native...

Description
Summary:	It was shown that the laccase (LC) included into hydrophobic ionic liquid (IL) can be reused for the biotransformation of dihydroquercetin (DHQ). The physicochemical characteristics of DHQ oligomers synthesized using LC/IL did not differ from the characteristics of the oligomers obtained with native laccase. The synthesized oligomers have a number average molecular weight of 1050 g/mol and a polydispersity index of 1.41. Oligomers possess higher antioxidant activity than the monomer.
