Techoic acids

Gram-positive organisms Mainly a mixed polymer of muramic acid and peptide techoic acids and polysaccharide... 

Many different types of carbohydrate-containing molecules are located on the surface of microbial cells. Some of these are components of the microbial cell wall and are limited to certain types of micro-organisms such as bacterial peptidoglycan, lipopolysaccharides, techoic acids and yeast mannans. Other polysaccharides are not... 

N-Ac 4-N-Acetylglucosaminylribitol C13H25NO10 355.341 The phosphate of this disaccharide is the repeating unit of Staphylococcus aureus techoic acid from which it is obt. by mild alkaline hydrolysis followed by dephosphorylation. On isol. the disac-charide is a mixt. of 1 ->-4 linked a and p isomers, the proportions varying from sample to sample of techoic acid. 

C11H22O10 314.289 Isol. from the hydrolysate (alkaline followed by phosphorylase) of Lactobacillus arabinosaceous techoic acid.
