Purpose. To anayze scientific sources on physiological-biochemical pecularities of reducing-oxidizing processes, including peroxide oxidation of lipids and work of the system of antioxidant protection system in sturgeon species (Acipenseridae). The initiation and process of the oxidative stress have been described. The main products of peroxide oxidation of lipids, antioxidants of natural and artificial origin, organs and tissues for the studies of reducing-oxidizing processes have been examined. Findings. The work generalizes the processes of lipid peroxidation. Briefly outlined the main mechanism of action of antioxidant enzymes. Antioxidant defense system plays one of key role in the life of organism due regulating its series of metabolic processes, use of assessing of its state gives an opportunity obtain quantitative information on the progress of these processes. The products of free radical peroxidation (dien conjugates and malonic dialdehyde) can also act as a sort of biomarkers of tissue damage, because their content can judge about the intensity of the flow of free radical processes in the various systems in organism. The review contains a description of the peculiarities of the liver and its involvement in lipid metabolism and antioxidant defense system. It is shown the most common antioxidants used in the feeding of sturgeon. Organs and tissues, which should be used for studying the processes of peroxide oxidation of lipids in sturgeon species, have been examined. Practical value. The systematized data regarding peroxide oxidation of lipids, oxidative stress and antioxidant protection system allow finding a balance between these processes. The data on antioxidants, which are used in feeds for sturgeon species, will be useful for sturgeon culturists. The array of the generalized information will be important for scientists who study the pecularities of the processes of peroxide oxidation of lipids and antioxidant protection system in sturgeon species.
