Teichoic acids glycerol

Fig. 1.3 A, glycerol teichoic acid B, ribitol teichoic acid G, 3-10 glycosyl Ala, D-alanyl.

The cell walls of most Gram-positive bacteria contain (1 ->3) poly(glycerol phosphate) teichoic acids which can bear D-alanyl or glycosyl substituents.56 However, the cell walls of Bacillus stearothermophilus B65 contain a glycerol teichoic acid which is free of substituents.57 This is contrary to evidence that had been obtained from biosynthetic studies.58...

Glycerol teichoic acids are more widely distributed than the ribitol compounds. Some of them appear to be located mostly in the region between the wall and the underlying protoplast membrane. For detailed stmctures of the various teichoic acids, the reader should consult reviews by Baddiley and coworkers and Baddiley. ... 

This relatively simple type of sequence is characteristic of the ribitol teichoic acids and many glycerol teichoic acids, as well as some related phosphorylated polysaccharides. Despite its simplicity the exact nature of the biosynthetic process is rather less well understood than is the case with the complex teichoic acids (above).
