phosphatidylethanolamines

Glycerophospholipids, cephalins (Phosphatidylethanolamines (egg)) 是一种从鸡蛋中分离出来的磷脂酰乙醇胺的混合物，在 sn-1和 sn-2位置有各种脂肪酰基。Glycerophospholipids, cephalins 完全水解可得到1mol 的甘油、磷酸、乙醇胺和2mol 的脂肪酸。Phosphatidylethanolamines 在膜融合和细胞分裂过程中收缩环的拆卸中起作用，可调节膜的弯曲度。Phosphatidylethanolamines 能够在没有任何蛋白质或核酸的帮助下传播传染性朊病毒。Phosphatidylethanolamines 在细菌膜中的主要作用之一是分散由阴离子膜磷脂引起的负电荷。

Phosphatidylethanolamine (PE) 是一种存在于哺乳动物体内的磷脂，通过磷酯酰丝氨酸的脱羧作用形成。

Phosphatidylethanolamines (bovine) 是从牛脑中分离出来的一种磷脂酰乙醇胺混合物，在 sn-1 和 sn-2 位置上带有不同的脂肪酰基。Phosphatidylethanolamines (bovine) 是在原核生物、哺乳动物、植物和酵母细胞膜中含量均很高的磷脂，约占哺乳动物磷脂总量的 25%。

Lysophosphatidylethanolamines (egg) 是磷脂酰乙醇胺的部分水解产物。

Phosphatidylethanolamines are important components of cell membranes and biochemical pathways of fatty acid synthesis. 1-Palmitoyl-2-linoleoyl PE (PLPE) is one of the many phosphatidylethanolamines that may be present in cellular membranes. It has been used in studies involving the biosynthesis of anandamide via the phospholipase A2 (PLA2) and lysoPLD pathways. PLPE can also be used as a specific substrate to assess the activity of sPLA2-IIA in the presence of other phospholipids.

1,3-Dipalmitoyl glycero-2-phosphatidylethanolamine is a phospholipid incorporating saturated long-chain (16:0) stearic acid at the sn-1 and sn-3 positions, with phosphatidylethanolamine (PE) at the sn-2 position. Phosphatidylethanolamines, critical components of biological membranes, play essential structural and functional roles. Various PE types are instrumental in forming micelles, liposomes, and other synthetic membranes.
