Sexual differences in galactose metabolism: galactosyl ceramide galactosidase and other galactosidases in mouse kidney (Short Communication)

摘要

Male and female mice were compared at two ages, 15 and 50 days, with respect to the activities of three galactosidases in kidney. No sex difference in enzyme activity was seen in the young mice, but appreciable differences were found in the older animals. The male kidneys had about one-third higher specific activities of cerebroside β-galactosidase and nitrophenyl β-galactosidase, but there was no difference with nitrophenyl α-galactosidase. A listing and discussion of other galactose-metabolizing enzymes influenced by sex differences is presented.
