An enzymatically active product for use in isomerization of glucose into fructose is provided. The active product comprises an organic polymeric material predominantly comprised of a monovinyl aromatic compound polymer having beta -aminopropionamidomethyl group as side chains represented by the formula I: <IMAGE> wherein R1 is selected from H, C(1-6) alkyl and C(2-6) hydroxyalkyl, R2 is selected from C(1-6) alkyl, C(2-6)hydroxyalkyl, <IMAGE> (where X, Z1 and Z2 are selected from H and C(1-6) alkyl, and n is from 2 to 6), or R1 and R2 form together with the N atom, to which R1 and R2 are bonded, a heterocylic structure of the formula: <IMAGE> where A is -CH2-, -O- or -NR6- (wherein R6 is H or C(1-6) alkyl), and R3, R4 and R5 are selected from H and methyl. The organic polymeric material has glucose isomerase immobilized with the beta -aminopropionamidomethyl group side chain of the organic polymeric material.
