In the work, certain metabolic parameters and parameters of functional senescence were studied in the fruit fly D. melanogaster w1118 males fed with alpha-ketoglutarate (AKG). Dietary increased levels of amino acids and protein in 2-day-old males and levels of triacylglycerols in 24-day-old males with no effect on antioxidant system of males of both age groups. In addition, AKG-supplemented food increased resistance to heat stress but not to oxidants in both age groups and prevented the decline in locomotor activity in middle-aged males.
