Antioxidative activity of carp blood plasma was estimated by measuring hydroperoxides formed by liposome peroxidation during the exposure of liposomes to AAPH. Ascorbic acid of high concentration, uric acid of low content, and tocopherol formed special protective system against lipid peroxidation in fish plasma. The decrease of uric acid, ascorbic acid, and tocopherol showed synergism of ascorbic acid and tocopherol, uric acid, and tocopherol. Carp blood plasma with a low concentration of protein (about 2%) and SH groups (88 muM) had a great effect on the antioxidative activity, as the effects of ascorbic acid, uric acid, and tocopherol were dramatically extended. Dialysed carp protein also displayed a very strong antioxidative activity on lipid peroxidation of a multilayer liposome system
