神经酰胺包括含 C14 至 C24 饱和和单不饱和脂肪酸酰基链的刺状脂肪。它们存在于大多数哺乳动物组织中 C24:1 神经酰胺 (d18:1/24:1 (15Z)) 已被用作液相色谱-质谱仪的内部支架。 也适合在高效液相色谱/串联质谱法中作为标准品使用 Ceramides comprise spingolipids with acyl chains of C14 to C24 saturated and monounsaturated fatty acids. They are present in most of the mammalian tissues. C24:1 Ceramide (d18:1/24:1(15Z)) has been used as an internal stand in liquid chromatography-mass spectrometer. It is also suitable for use as a standard in high-performance liquid chromatography/tandem mass spectrometry.
