description: "A branched polysaccharide composed of a backbone of repeating beta-L-rhamnosyl-(1->4)-beta-D-glucosyl-(1->3)-[alpha-D-glucuronosyl-(1->6)-alpha-D-glucosyl-(1->2)]-alpha-L-rhamnosyl-(1->3)-alpha-L-rhamnosyl units, joined by (1->3) linkages. The repeating unit is that of the Streptococcus pneumoniae serotype 2 capsular polysaccharide."
