CHARACTERIZATION OF ACYLPHOPHATIDYLGLYCEROLS FROM SALMONELLA TYPHIMURIUM BY TAN

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。酰基磷脂酰甘油（acyl - pg）是一种含有3个脂肪酰基的极性脂类化合物，从沙门氏菌中分离得到，并采用tander四极杆和四极杆离子阱质谱技术和电喷雾电离技术对其进行了表征。具有不同酰基的酰基- pg （A-B/C- pg，其中A不等于B不等于C）的结构表征是基于sn-2 (R(x)CO（2)(-)）产生的羧酸阴离子(R(x)CO（2)(-)）比sn-3'(R(3')CO（2)(-)）产生的羧酸阴离子(R(x)CO（2)(-)）丰富，比sn-1 (R(1)CO（2)(-)）产生的羧酸阴离子(R(x)CO（2)(-)）丰富得多。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Acylphosphatidylglycerol (Acyl-PG), a polar lipid class containing three fatty acyl groups, was isolated from Salmonella bacteria and characterized by tander quadrupole and quadrupole ion-trap mass spectrometric methods with electrospray ionization. The structural characterization of the acyl-PG with various acyl groups (A-B/C-PG, where A not equal B not equal C) is based on findings that the carboxylate anions (R(x)CO(2)(-)) arrising from sn-2 (R(x)CO(2)(-)) is more abundant than that arising from sn-3'(R(3')CO(2)(-)), which is much more abundatnt than that arising from sn-1 (R(1)CO(2)(-)).
