title: An interspecies comparison of gangliosides and neutral glycolipids in adrenal glands.
abstract: Gangliosides and neutral glycolipids of adrenal glands of mouse, rat, guinea pig, rabbit, cat, pig, cow, monkey, and chicken were analyzed by thin layer chromatography (TLC). The major gangliosides common to all species had lactosylceramide in their core structure. GM3 containing N-acetylneuraminic acid (NeuAc) was the major ganglioside in rat, guinea pig, rabbit, and cat, whereas GM3 containing N-glycolylneuraminic acid (NeuGc) was the major one in mouse, cow, and monkey. GD3 was also detected in all species except mouse and GD3(NeuAc)2 was the major in pig adrenal gland. GM4(NeuAc) was detected in the adrenal glands of guinea pig and chicken but not in those of the other species. In the neutral glycolipid fractions, galactosylceramide, glucosylceramide, lactosylceramide, globotriaosylceramide and globotetraosylceramide were detected and the proportions of these glycolipids varied among the species. Guinea pig and chicken adrenal glands contained large amounts of galactosylceramide, this being consistent with the presence of GM4 in these two species. Globopentaosylceramide was detected in mouse, guinea pig, cat, and chicken by the TLC-immunostaining procedure.
