Carbohydrate-protein biopolymers fromPseudopterogorgia americana

A carbohydrate-protein biopolymer which has been called corallan has been isolated from the soft coralP. americana. It has been shown that corollan consists of a proteoglycan including a protein component and a polysaccharide component connected with one another by a fairly strong bond. The polysaccharide moiety is a sulfated glycuronoglycan containing residues of fucose, arabinose, galactose, glucose, and a uronic acid and, possibly, also of aminosugars.
