Bioehem. 52, 689-697Structural studies on the major glycolipid of rat testis have confirmed our earlier identification of this compound as a 1-0-alkyl-2-0-acyl-glyce~yl-monogaIactoside sulfate. The acyl and alkyl groups are predominantly palmitoyl and palmityl groups, respectively. %he minor glycolipid found in the same tissue has been identified as the non-sulfated form of this glycolipid. Examination of the levels of the sulfoglycerogalactolipid in the testes of immature rats, hypophysectomized rats, and normal and sterile mice indicates that the majority of the compound is located in the germinal cells of the testis and that the primary spermatocytes are the earliest spermatogenic cells to contain high levels of the lipid. Galactolipid sulfotransferase also shows peak activity in the primary spermatocytes of rat testis. Kornblatt, M. J., Knapp, A., Levine, M., Schachter, H. &Murray, R. K.

L'examen des taux de sulfoglyc6rogalactolipide dans les testicules de rats non matures, de rats hypophysectomists, de souris sttriles et de souris nomales montre que la plus grande partie de ce cornperst se situe dans les cellules germinales des testicules et que les spermatocytes primaires ssnt les premieres cellules spermatogbnes i contenir des quantitts 6levtes de ce ligide.

In the present report, we present further monsacyl-glyceryl-monogdactoside sulfate. data on the structures of the sulfoglycerogalacIshiauka et al.

Since pig testes and have established its structure to be a 1-0-alkyl-2-0-acyl-3-P(3'-sulfogalactosyl)-glycerol. This novel compound is present in substantial amounts in the testes of the rat, mouse, guinea pig, rabbit, pig, and we
