Their compositions were proved by elemental analysis for C, H, N, and P. IR, PMR, C-13 NMR, and P-31 NMR spectroscopy and potentiometric titration showed that the complexes of phytic acid and glucosamine were formed by H-bonds and electrostatic salt interactions. High antioxidant activity against lipid peroxidation and a positive effect on superoxide dismutase activity were found for complexes of InsP(6)H(12) and glucosamine in in vitro studies of human blood plasma under oxidative stress.</p></abstract_text> 收起
