Chicken egg yolk was found to contain a unique glycosphingolipid pattern not seen in other types of tissue or cell. These glycosphingolipids were isolated in pure form and their structures established by sequential enzymic hydrolysis and permethylation analysis. The major gangliosides in chicken egg yolk are N-acetylneuraminosylgalactosylceramide, N-acetylneuraminosyl-lactosylceramide and di-N-acetylneuraminosyl-lactosylceramide. The only neutral glycosphingolipid found in chicken egg yolk is galactosylceramide.
研究发现，鸡卵黄中含有一种独特的糖鞘脂模式，在其他类型的组织或细胞中未见。这些糖鞘脂以纯形式分离出来，其结构通过顺序酶解和全甲基化分析确定。鸡卵黄中的主要神经节苷脂是N-乙酰神经氨酰半乳糖基神经酰胺、N-乙酰神经氨酰乳糖基神经酰胺和二-N-乙酰神经氨酰乳糖基神经酰胺。鸡卵黄中发现的唯一中性糖鞘脂是半乳糖基神经酰胺。
