一般描述

鞘磷脂（SM）是哺乳动物细胞膜中的主要鞘脂。已经研究了它的生物学功能。

应用

鞘磷脂适合使用：
  • 在酶法测定血浆鞘磷脂水平的标准制备品中
  • 研究血管抗凝血剂 α（VAC α）与平面磷脂双分子层的结合
  • 对联合超声处理的卵磷脂和鞘磷脂的分散体中的 PC16（N- [α-N-棕榈酰-ε-N-（4-硝基苯并-2-氧杂-1，3-二唑）-L-赖氨酸] -2-氨基乙醇-N-（三甲基氨基乙醇）磷酸盐）的进行荧光偏振
  • 用于将病毒离子通道蛋白 M2 重建成脂质体
  • 作为使用飞行时间二次离子质谱（ToF-SIMS）定义光谱指纹的标准样品
  • 评估各种磷脂对羊水中泡沫形成的贡献

生化/生理作用

鞘磷脂是 HDL 和质膜中第二丰富的脂质和主要的鞘脂成分。它形成富含胆固醇的脂筏。它在无质膜胆固醇的可用性中起关键作用。

分析说明

主要含有棕榈酸。

The mechanism of a new fluorescence polarization method for measuring phospholipid in amniotic fluid is described. The fluorescence polarization of a surfactant fluorescent dye solubilized in amniotic fluid correlates significantly with the L/S ratio. Model studies indicate that this results

We evaluated the relative contributions of various phospholipids to the formation of foam in the amniotic fluid "foam stability test", by use of an artificial system of saline, ethanol, and dipalmitoyl 3-sn-phosphatidylcholine to determine the relationship between dipalmitoyl 3-sn-phosphatidylcholine concentration

Vascular anticoagulant alpha (VAC alpha, annexin V) is a member of the family of calcium and phospholipid binding proteins, the annexins. The binding properties of VAC alpha to phospholipid bilayers were studied by ellipsometry. Adsorption was calcium-dependent and completely reversible

The tumour necrosis factor alpha (TNF), has been implicated in the pathogenesis of non-steroidal anti-inflammatory drug (NSAID) induced gastropathy and Helicobacter pylori induced gastritis. Both conditions are characterised by high plasma pepsinogen concentrations, which are thought to reflect an increased
