This study examines the activity of antioxidant enzymes glutathione reductase (GR) and superoxide dismutase (SOD), as well as the content of reduced glutathione (GSH), amino acids, and pyruvate in the hepatopancreas, gills, and foot of the Black Sea hemoglobin-containing bivalve Anadara kagoshimensis (Tokunaga, 1906) (Bivalvia: Arcidae). The highest level of GSH and the lowest activity of SOD and GR were found in the foot of the mollusk. In hepatopancreas and gills, the activity of these enzymes was highest but the content of GSH was substantially lower than in foot. The content of pyruvate and amino acids decreased in the series hepatopancreas - gills - foot. The peculiarities of the interrelation between antioxidant enzymes and low molecular antioxidants, as well as the role of the latter in the energy supply of A. kagoshimensis under oxygen deficiency in the intertidal zone are discussed.

Key words: glutathione, glutathione reductase, superoxide dismutase, pyruvate, amino acids, Anadara kagoshimensis, Black Sea.
