Abstract

The main acidic glycosphingolipids (GSLs) of cock testis were identified as GalCer I3-sulfate and gangliosides GM4, GM3, GD3 and GT3. They contained N-acetylneuraminic acid as the major sialic acid, and ceramides composed mainly of sphingosine (dl8:1) and C18-24 non-hydroxy fatty acids. Appreciable amounts of hydroxy fatty acids were detected only in the GM4 preparation.

摘要

公鸡睾丸的主要酸性糖鞘脂（GSLs）被鉴定为硫酸化半乳糖脑苷脂I3和神经节苷脂GM4、GM3、GD3和GT3。它们以N-乙酰神经氨酸作为主要唾液酸，并且神经酰胺主要由鞘氨醇（dl8:1）和C18 - 24非羟基脂肪酸组成。仅在GM4制剂中检测到了可观量的羟基脂肪酸。
