Collision-induced dissociation (CID) spectra of sodium ion complexes ([M+Na]+ ions), produced by FAB-MS of methyl ester derivatives of ganglioside, indicate the length of the fatty acyl chain of the ceramide moieties without chemical degradation. In the case of a genuine ganglioside, only the fission of the glycosyl linkage of sialic acid was prominently observed.
通过神经节苷脂甲酯衍生物的快原子轰击质谱(FAB-MS)产生的钠离子复合物([M + Na]+离子)的碰撞诱导解离(CID)光谱,可在不发生化学降解的情况下表明神经酰胺部分的脂肪酰链长度。对于真正的神经节苷脂,仅显著观察到唾液酸糖基键的断裂。
