and versatile methods for the determination of the absolute configuration of the chiral glycerol components. Only in a few instances has the assignment of the stereochemistry of 0-glycosyl glycerol, phosphorylated at one of the primary hydroxymethyl groups, within this type of polymer been reported 12-15 On the other hand, the stereochemistry of the . teichoic acids in the cell walls and membranes of
然后将其转化为合适的衍生物,并通过与已知手性标准品的比较,通过分光光度法CORD,CD或NMR分配绝对立体化学),色谱或酶促方法18,19。如果聚合物是通过+ l)-甘油-(3 +磷酸二酯键连接的,则可以用HF水溶液进行解聚,得到1-0-糖基化的甘油片段,然后可以通过将色谱性质与标准品进行比较来进行构型分析。已知的绝对构型2'或氧化为相应的手性甘油酸后通过立体定向酶分析21基于从1获得的2,3-二-0-苄基-sn-甘油的手性性质测量方法已经描述了-0-糖基-sn-甘油。
