Inulin is a naturally occurring polysaccharide. The production of a capsular polysaccharide decreases biofilm formation. This endosperm consists of a large polysaccharide of galactose and mannose. The body is protected by a translucent carapace made of chitin, a transparent polysaccharide. A polysaccharide called pectin is used as a gelling agent. Disease-causing strains are classified according to the antigenic structure of their polysaccharide capsule. Alginate's ability to scaffold and makes it a novel polysaccharide. A chain of monosaccharides form to make a polysaccharide. Many monosaccharides joined together form a polysaccharide. Sucrose is the only sugar that bacteria can use to form this sticky polysaccharide. It contains a nutritious starch-like polysaccharide called glucomannan. The second is K antigen, a capsular polysaccharide with more than 80 varieties. Ascidians are characterized by a tough outer "tunic" made of the polysaccharide cellulose. This is when glycosylation and polysaccharide synthesis occur. Certain strains of "S. haemolyticus" are capable of producing a capsular polysaccharide (CP).
