Synonyms: O antigen anabolism, O antigen biosynthesis, O antigen formation, O antigen synthesis

Definition: The chemical reactions and pathways resulting in the formation of the O side chain of a lipopolysaccharide, which determines the antigenic specificity of the organism. It is made up of about 50 repeating units of a branched tetrasaccharide.
