Microbial Carbohydrates

Microbial Carbohydrates


There are considerable differences between bacterial and mammalian glycans. In contrast to the most eukaryote, bacterial glycans are usually composed of a large number of repeating units. The bacteria cell wall is based on peptidoglycan network macromolecular structure, that is, a polypeptide chain, in which polysaccharide chains are cross-linked with short peptide chains. Gram-negative bacteria have an outer wall composed of lipopolysaccharide-protein complexes. Lipopolysaccharide contains lipid A, the phosphorylated GlcN-GlcN disaccharide, and N- and O-acylated with fatty acids that anchor the molecule in the leaflet of the outer membrane.

Since these repeating units are usually displayed on the cell surface, they can interact with the environment. These carbohydrates also contain antigenic determinants, can elicit an immunogenic response in the host, and can provide identification elements for pathogens such as phages. We provide services on bacterial surface carbohydrates to help expand the general knowledge and understanding of the complexity of glycans in biological systems, which will provide a basis to design high-throughput vaccines, develop diagnostics and immunostimulants.
