The most abundant phospholipid in many cells is phosphatidyl ethanolamine or cephalin. 在许多细胞中,含量最高的磷脂是磷脂酰乙醇胺或脑磷脂。
OBJECTIVE To study and improve the synthesis of liposome excipient phosphatidyl ethanolamine. 目的研究并改进脂质体辅料磷脂酰乙醇胺的合成工艺。
The effects of initial water content in silica-gel and the water content of mobile phase on the simultaneous purification of Phosphatidyl Choline ( PC) and Phosphatidyl Ethanolamine ( PE) by silica-gel column chromatography were studied systematically. 研究了固定相初始含水量和流动相含水量对硅胶柱层析同时分离纯化卵磷脂和脑磷脂的影响。
Thin-layer chromatographic analysis indicated the contents of lecithin and phosphatidyl ethanolamine in deteriorative phosphatide were reduced visibly. 薄层色谱分析表明:变质磷脂中卵磷脂、脑磷脂含量明显减少。
Results The results revealed that the ethanolamine into phosphatidyl ethanolamine demonstrated specificity in tissues. The biosynthesis power in brain was prominent ( 38.3%) and followed by liver and kidney tissues. Less power was seen in heart tissues with a percentage of 12.1%. 结果显现标记乙醇胺进入磷脂酰乙醇胺具有组织特异性,大脑中磷脂酰乙醇胺的生物合成能力最强,占38.3%,其次为肝脏和肾脏,合成能力最弱的是心脏,仅占12.1%。
Both Phosphatidyl Choline ( PC) and Phosphatidyl Ethanolamine ( PE) are important sorts of phospholipids, being widely used in the filed of food, pharmacy, cosmetic and so on. 卵磷脂(PC)和脑磷脂(PE)是其中两种重要的磷脂,被广泛应用于食品、医药、化妆品等行业。
Lipopolysaccharide ( LPS) and phosphatidyl ethanolamine ( PE) are the major components in cell membranes of most Gram-negative bacteria. 脂多糖和磷脂酰乙醇胺是革兰氏阴性细菌细胞膜的主要组分。
