Marine algae, polysaccharides from

It is of interest to note that the crystalline barium heparinate, which is an acid salt, tends to lose its anticoagulant powers very readily and that the authors consider that sulfur content gives no indication of heparin activity.93 Some polysaccharide sulfuric esters from marine algae possess anticoagulant activity.

Structural polysaccharides exhibit properties that are dramatically different from those of the storage polysaccharides, even though the compositions of these two classes are similar. The structural polysaccharide cellulose is the most abundant natural polymer in the world. Found in the cell walls of nearly aU plants, included marine algae, cellulose is one of the principal components, providing physical structure and strength [1]. 

A polysaccharide from the green marine alga Ulva lactuca inhibited the reproduction of many human and avian influenza viruses. Acid hydrolysis of this polysaccharide revealed the presence of arabinose, xylose, rhamnose, galactose, mannose and glucose in ratio of 1 1 9 5 2 5 16, respectively along with an unidentified sugar [218].
