一般描述

磷脂酰胆碱属于甘油糖脂类，含有胆碱头基。[1]胆碱连接至与主链结合的脂肪酸酯的甘油上。[1][2]它是真核生物中存在的主要磷脂。[2]

应用

L-α-磷脂酰胆碱已：
  • 用于通过脂质体包裹的氯膦酸盐,形成用于Kupffer细胞去除的薄脂质膜[3]
  • 作为γ-分泌酶体外测定所用的测定缓冲液组分[4]
  • 用于制备5-脂氧合酶活性HPLC（高效液相色谱）测定的底物混合物[5]

生化/生理作用

它还充当脂质信使/生物活性脂质来源，包括：溶血磷脂酰胆碱、二酰基甘油、磷脂酸、溶血磷脂酰胆碱、花生四烯酸和血小板活化因子。[6]磷脂酰胆碱在肝脏中通过CDP-胆碱（胞苷二磷酸胆碱）途径产生。[7]
脑磷脂脑中的主要结构磷脂，包含脂肪总量的约15%；主要局限于灰质。

包装

在氩气下包装

制备说明

制备参照 Singleton, W.S. 等人刊登于 J. Am. Oil Chem. Soc., 42, 53 (1965) 的工艺，并加以改进。

    Nosocomial infections with Enterococcus faecalis are an emerging health problem. However, drug efflux pumps contributing to intrinsic drug resistance are poorly studied in this Gram-positive pathogen. In this study, we functionally investigated seven heterodimeric ABC transporters of E. faecalis that
