Techoic acids

• The techoic acids (ribitol and glycerol phosphates) are a family of large molecular weight polymers which are found mostly in gram +ve bacteria and are located in the membrane and the wall. They are grouped mainly as the wall techoic acids and the membrane techoic acids although originally the word ‘teicho’ was given to indicate their presence only in the wall.
