teichoic acids

 [ti-ko´ik]
antigenic polymers of glycerol or ribitol phosphates found attached to the cell walls or in intracellular association with membranes of gram-positive bacteria; they determine group specificity of some species, e.g., the staphylococci.

tei·cho·ic ac·ids

(tī-kō'ik as'idz),
One of two classes (the other being the muramic acids or mucopeptides) of polymers constituting the cell walls of Gram-positive bacteria, but also found intracellularly; linear polymers of a polyol (ribitol phosphate or glycerol phosphate) carrying d-alanyl residues esterified to OH groups and glycosidically linked sugars.

The cell wails of pneumococci contain special polymers, called teichoic acids, that are equipped with phosphocholine groups and induce a characteristic choline architecture on the cell walls.
Phosphonates and teichoic acids may be derived from lysis products of microorganisms (Condron et al.
Diester-P, phosphonates, and teichoic acids were positively correlated to aromatic and phenolic C (all decreasing with depth) and negatively to O-alkyl C (increasing with depth).
Cell Wall Teichoic Acids in the Taxonomy and Characterization of Gram-Positive Bacteria
EPC decay pattern for a Gram-positive bacterium FS was distinguished by complex structure of cell wall, peptidoglycan layers, and teichoic acids made of alcohol and phosphate groups.
The exocellular lipoteichoic acid is significantly more active than that of lipoteichoic acid, peptidoglycan or wall teichoic acid, especially for TNF-[alpha] and nitric oxide production.
