[Glycosphingolipids of human aorta].
The structures of the main gangliosides of human aorta (intima and media) were elucidated. The main component (67%) was identified as N-acetylneuraminosyl-lactosylceramide (ganglioside GM3). The aorta tissue contained also gangliosides GM1, GD3, GD1a, and GT1. All sialic acid residues in gangliosides were present as N-acetyl-neuraminosyl derivatives. Among neutral glycosphingolipids of human aorta, the main components were identified as glucosylceramide, lactosylceramide, globotriaosylceramide and globotetraosylceramide. The preliminary data suggest that the composition of the investigated glycosphingolipids in tissue might vary upon atherosclerosis lesions of aorta.
