title: [ELEMENTS OF THE LOW MOLECULAR WEIGHT CHAIN OF ANTIOXIDANT DEFENSE IN TISSUES OF THE BLACK SEA MOLLUSC ANADARA KAGOSHIMENSIS BRUGÙIERE].
abstract: The content of reduced glutathione (GSH) and the activity of the coupled with it antioxidant enzymes - glutathione peroxidase and glutathione reductase as well the level of glucose, carbamide and amino acids were investigated in the hepatopancreas, gills and foot of the Black, Sea mollusk Anadara kagoshimensis. The highest content of GSH and the highest activity of glutathione peroxidase were found in mollusk foot, evidencing the active antioxidant role of glutathione played both within composition of this enzyme and independently. The maximal content of glucose, amino acids and carbamide was in the hepatopancreas and gills and the minimal - in the anadara's foot. The possible involvement and role of these low molecular weight antioxidants in the defense of mollusk tissues against action of free radical oxidation and in providing adaptation reactions of anadara in hypoxic habitats are considered. Key words: antioxidant complex, glutathione, glucose, carbamide, amino acids, anadara Anadara kagoshimensis, Black Sea.
