Abstract
The synthesis and turnover of sulfogalactoglycerolipid (SGG) [in rat tests] were studied by in vivo labeling of SGG [sulfogalactoglycerolipid] with 35S. The loss of [35S]SGG from the testes and its appearance in the vas deferens plus epididymis were followed with time. DNA was labeled by administration of [3H]thymidine and the behavior of the 2 isotopes was compared. SGG synthesis apparently occurs only in very early spermatocytes and that, once made, the compound does not turn over. The SGG is lost from the testes when germinal cells die or mature into spermatozoa.This publication has 2 references indexed in Scilit:
