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
L-α-Phosphatidylethanolamine from egg yolk has high unsaturated fatty acid content and elicits radical-scavenging activity. L-α-Phosphatidylethanolamine (PE) is a membrane phospholipid and is interconverted to phosphotidylserine in the presence of phosphatidylserine synthase 2. PE is essential for maintaining the structural integrity of membranes. It is the second most abundant phospholipid in animals, plants and yeast and the major lipid in bacteria. It is synthesized in mitochondria in mammals.
Application
L-α-Phosphatidylethanolamine from egg yolk has been used: as a component of lipid mixture for the synthesis of giant unilamellar vesicles (GUVs) in ceramide phosphoethanolamine (CPE) synthase assay using crude sphingomyelin synthase-related protein from Hela cells for the standard curve generation for the quantification of lipids in plantaris muscle homogenates from mice
