title: [The ratio of processes of lipid peroxidation and antioxidant activity in gonads of Elasmobranchia and teleost fishes of the Black Sea].
abstract: It has been found that gonads of sharks contain higher content of alkoxylipids and vitamin K and lower levels of monoglycerides and carotenoids than gonads of teleost fishes. The peroxidase activity is higher in gonads of shark males but the glutathione reductase activity is lower. No significant differences in lipids peroxidation indices in gonads of elasmobranchia and teleosts were found. The total antioxidant activity of lipids in gonads of shark males exceeds 1, while the same indices of teleosts are below 1. Differences in the lipid composition, antioxidant enzyme activities, the content of glutathione, carotenoids, vitamins A, E, K and lipid peroxidation in male and female fish gonads are described. Correlation coefficients for all indices of the lipid peroxidation and antioxidant activity are estimated.
