Walls of Staphylococcus epidermidis I2 contain 30% (w/w) of a glycerol teichoic acid containing phosphate, d-alanine and d-glucose in the molecular proportions 1:0.25:0.50. 2. The teichoic acid was isolated by extraction with trichloroacetic acid and with dilute aqueous NN-dimethylhydrazine at pH7, and was shown to be a (1-->3)-linked poly(glycerol phosphate) containing beta-d-glucopyranosyl and d-alanyl ester substituents. 3. 2-O-beta-d-Glucopyranosylglycerol was isolated and characterized as its crystalline hexa-O-acetate. 4. Unlike that of certain other bacteria, the peptidoglycan component of the wall is not solubilized by NN-dimethylhydrazine. 5. The membrane teichoic acid is also a (1-->3)-linked poly(glycerol phosphate) but contains a smaller proportion of glucosyl substituents.

表皮葡萄球菌I2的细胞壁含有30%（w/w）的甘油磷壁酸，其分子比例为磷酸盐∶d - 丙氨酸∶d - 葡萄糖 = 1∶0.25∶0.50。
通过用三氯乙酸和pH7的稀NN - 二甲基肼水溶液萃取分离出磷壁酸，结果表明它是一种含有β - d - 吡喃葡萄糖基和d - 丙氨酰酯取代基的（1→3）连接的聚（甘油磷酸）。
分离出2 - O - β - d - 吡喃葡萄糖基甘油，并将其表征为其结晶六 - O - 乙酸酯。
与某些其他细菌不同，细胞壁的肽聚糖成分不会被NN - 二甲基肼溶解。
膜磷壁酸也是一种（1→3）连接的聚（甘油磷酸），但含有较小比例的葡萄糖基取代基。
