一般描述
蛋黄中的L-α-磷脂酰乙醇胺具有较高的不饱和脂肪酸含量，并具有自由基清除活性。L-α-磷脂酰乙醇胺(PE)是一种膜磷脂，在存在磷脂酰丝氨酸合酶2的条件下可与磷脂酰丝氨酸相互转化。PE对于维持膜结构完整性至关重要。它是动植物和酵母中含量第二丰富的磷脂，也是细菌中的主要脂质。它在哺乳动物的线粒体中合成。
应用
蛋黄中的L-α-磷脂酰乙醇胺已用于：
- 用作脂质混合物组分，以合成巨型单层囊泡(GUV)
- 使用Hela细胞来源粗鞘磷脂合酶相关蛋白的神经酰胺磷酸乙醇胺（CPE）合酶测定
- 生成小鼠足底肌肉匀浆中脂质定量标准曲线
包装
在氩气下包装。
注意
制备时纯度为 97-99%。该溶液暴露在室温下每天可分解 0.3-0.5%。

Sphingomyelin synthase-related protein (SMSr) synthesizes the sphingomyelin analog ceramide phosphoethanolamine (CPE) in cells. Previous cell studies indicated that SMSr is involved in ceramide homeostasis and is crucial for cell function. To further examine SMSr function in vivo, we generated Smsr
