1. The Group A, B and O mucopolysaccharides differ from one another in glucosamine/galactosamine ratio. The Group A and O substances resemble each other and the Group B substance diverges from them in sialic acid content. The corresponding analytical figures of the other sugar components are similar to one another among the three muco-polysaccharides. As for optical rotation, the Group A substance is dextrorotatory, while the B and O substances are levorotatory and that to like extents.
2. The O enzyme from B. fulminans destroys the Oactivity of all the group mucopolysaccharides, accompanied by splitting off of a part of L-fucose and reduction of glucosamine/galactosamine ratio.
