DefinitionA polysaccharide derivative comprising a tetrasaccharide repeating unit consisting of a trisaccharide backbone of β-D-galactosyl, β-D-glucosyl and N-acetyl-β-D-glucosaminyl residues linked sequentially (1→4) and (1→6), with a further β-D-galactosyl residue linked (1→4) to the N-acetyl-β-D-glucosaminyl residue, and with the tetrasaccharide repeats themselves being linked (1→3); corresponds to the serotype 14 capsular polysaccharide (CPS) of Streptococcus pneumoniae. The structure diagram shows a portion of the polysaccharide chain consisting of three such tetrasaccharide repeating units showing clearly the (1→3) linkages existing between the repeating units.
