teichoovými
Teichoic acids are polymers found in the cell walls of Gram-positive bacteria. They are anionic polymers composed of repeating units of either glycerol phosphate or ribitol phosphate, linked by phosphodiester bonds. These repeating units can be further modified with various substituents, such as D-alanine, D-glucosamine, or D-galactose, which can influence the properties of the cell wall and the interaction of the bacterium with its environment. Teichoic acids are covalently linked to the peptidoglycan layer of the cell wall and can also be attached to the cytoplasmic membrane via a lipid moiety, in which case they are termed lipoteichoic acids.
The primary functions of teichoic acids are related to the structural integrity of the Gram-positive cell wall.
