Abstract
The anomeric configurations of Corbicula ceramide dihexoside and ceramide trihexoside were determined by chromium trioxide oxidation and the structures of these lipids were shown to be Man-beta(1 leads to 4)-Glc-beta(1 leads to 1)-ceramide and Man-alpha(1 leads to 4)-Man-beta(1 leads to 4)-Glc-beta(1 leads to 1)-ceramide. These results are compatible with those obtained by enzymic hydrolysis reported previously.
摘要
通过三氧化铬氧化法确定了蚬酰胺二己糖苷和酰胺三己糖苷的端基构型，结果表明这些脂质的结构分别为甘露糖-β(1→4)-葡萄糖-β(1→1)-神经酰胺和甘露糖-α(1→4)-甘露糖-β(1→4)-葡萄糖-β(1→1)-神经酰胺。这些结果与先前报道的酶促水解结果一致。
