SORBITOL DEHYDROGENASE ACTIVITY IN SPERMATOZOA OF THE DOMESTIC FOWL, GALLUS DOMESTICUS

Polyol dehydrogenases play an important part in the mutual transformation of sugars and polyhydric alcohols in animal tissues and cells, vertebrate spermatozoa being of particular interest in this respect. The biochemical investigations, carried out by Mann & White (1956), King & Mann (1958, 1959), Slesingr (1961) and Hankiewicz, Hankiewicz, Hanus & Szaflarchi (1964), concerned the sorbitol dehydrogenase activity in the spermatozoa of a number of different mammals. The results of these investigations, however, do not explain sufficiently the full significance of the sorbitol dehydrogenase activity in sperm metabolism. The data on polyol dehydrogenase activity in fowl spermatozoa are sparse. Sorbitol dehydrogenase activity in the spermatozoa of the domestic fowl has been investigated chemically by Buckland (1970). No histochemical studies on the localization of polyol dehydrogenase in vertebrate spermatozoa
