Application
C18 神经酰胺（d18:1/18:0）已用于：
- 诱导 Manduca 胚胎细胞系（MRRL-CH1）中细胞凋亡
- 。其用作采用液相色谱-质谱法检测肝组织中神经酰胺的量的标准品，目的是
- 抑制发生β-葡糖脑苷脂酶（GCase）突变的人胚肾细胞（HEK29）中的神经酰胺酶。
Biochem/physiol Actions
在神经退行性病变中，基于 C18 神经酰胺的衍生物的量较少。它有利于胶质瘤细胞中基于内质网的应力和自噬。少量的C18-神经酰胺，也可影响人头颈部鳞状细胞癌。C18 神经酰胺可抑制肿瘤进展。
General description
C18 神经酰胺 (d18：1/18：0) 合成由神经酰胺合成酶 (CER) 1 和 5 催化。它是细胞膜的组成部分，而与不饱和神经酰胺相比，它的凝胶形成能力低。
