Definition:	A polysaccharide composed of a backbone of linear trisaccharide repeating units consisting of alpha-L-rhamnose, alpha-D-galactose and alpha-D-mannose residues linked sequentially (1->3) and (1->2), the repeating units being joined to each other via alpha(1->2)-linkages; corresponds to the backbone of the O-antigen repeat unit of the O:12 antigen common to Salmonella serogroups A, B and D.
