Wall teichoic acid (WTA) was isolated from Enterococcus faecalis 12030, a clinical isolate and biofilm-producing strain, and analyzed using compositional chemical methods, nuclear magnetic resonance spectroscopy, and mass spectrometry. The repeating units of WTA were composed of D-glucose, D-galactose, 2-acetamido-2-deoxy-D-galactose, 2-acetamido-2-deoxy-D-glucose, D-ribitol, and phosphate in a molar ratio 1:2:1:1:1:1, and had the structure given below.
从临床分离株和生物膜形成菌屎肠球菌 12030 中分离到壁磷壁酸（WTA），并用组成化学分析、核磁共振波谱和质谱进行了分析。WTA 的重复单元由摩尔比为 1:2:1:1:1:1 的 D-葡萄糖、D-半乳糖、2-乙酰氨基-2-脱氧-D-半乳糖、2-乙酰氨基-2-脱氧-D-葡萄糖、D-核糖醇和磷酸盐组成，其结构如下所示。
