Abstract

Three teichoic acids have been isolated from Bacillus licheniformis. Their structures were found to be 1,3 poly(glycerolphosphate), -->3)-alpha-D-Gal p-(1-->1)-L-glycerol- (3-->phosphate, and -->3)-[beta-D-Glc p-(1-->2)]-alpha-D-Gal p-(1-->1)-L-glycerol- (3-->phosphate. Without separating the individual teichoic acids, and despite their high molecular weight, these polysaccharides could be identified by modern NMR techniques alone.

摘要

已从地衣芽孢杆菌中分离出三种磷壁酸。发现它们的结构分别为1,3-聚（甘油磷酸）、→3)-α-D-半乳糖p-(1→1)-L-甘油-(3→磷酸，以及→3)-[β-D-葡萄糖p-(1→2)]-α-D-半乳糖p-(1→1)-L-甘油-(3→磷酸。无需分离单个磷壁酸，尽管它们分子量很高，但仅通过现代核磁共振技术就能鉴定出这些多糖。
