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 β-aminopropionamidomethyl group as side chains represented by the formula I:
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,
(where X, Z, and Z2 are selected from H and C(1-6) alkyl, and n is from 2 to 6), or R, and R2 form together with the N atom, to which R1 and R2 are bonded, a heterocylic structure of the formula:
where A is -CH2-, -O- or-NR6- (wherein R6 is H or C(1-6) alkyl), and R3, R4 and Rs are selected from H and methyl. The organic polymeric material has glucose isomerase immobilized with the β-aminopropionamidomethyl group side chain of the organic polymeric material.
