Abstract
Addition of egg yolk to washed and unwashed spermatozoa stimulated the activity of their succinic, malic, and glyceraldehyde-3-phosphate dehydrogenases. This stimulation was thought to be beneficial to sperm survival and persistence of motility, confirming the finding that boiled milk stimulates dehydrogenase activity; whereas unboiled milk fails to do so. The dehydrogenase-stimulating factor in egg yolk was associated with the acetone-soluble portion. Cholesterol stimulated succinic dehydrogenase activity but inhibited that of the other 2 enzymes. Carotene stimulated both succinic and malic and gave variable effects upon the 3d dehydrogenase under consideration.This publication has 36 references indexed in Scilit:
