Seaweed, polysaccharides from

This seaweed became known as Irish moss. The extraction and purification of the polysaccharide from Irish moss was patented in 1871 (29). This polysaccharide eventually became known as carrageenan it was not produced and marketed until 1937. 

Detergent Methods. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) methods (2), later modified for human foods (13), measure total insoluble plant cell wall material (NDF) and the cellulose—lignin complex (ADF). The easily solubilized pectins and some associated polysaccharides, galactomaimans of legume seeds, various plant gums, and seaweed polysaccharides are extracted away from the NDF. They caimot be recovered easily from the extract, and therefore the soluble fiber fraction is lost. 

The function of the sulfate residue in these polysaccharides is unknown but the suggestion has been made that just as starch is synthesised from D-glucose 1-phosphate by the action of phosphorylase, so the seaweed polysaccharides are formed from the appropriate sugar sulfate by reaction with a sulfatase. ...

A recently developed method for preparing the epimerie D-glucometasaccharinic acids is based on the action of lime-water on the seaweed polysaccharide, laminarin. The mixed D-glucometasaccharinic acids are obtainable from this source in practically pure condition, as their calcium salts, after separation from unchanged polysaccharide. The directions for their preparation from insoluble laminarin follow.

On a commercial scale, only polysaccharides from natural sources such as land plants and seaweeds are used. Medical applications, however, stimulate research on synthetic polysaccharides, which could be used as well defined models for studying the biological functions of different polysaccharides.
