Poly derivatives pectin

Carbohydrates have demonstrated an increasing role in tumor biology, with a known correlation between the expression of the ga-lectin 3 receptor and the propensity for metastatic spread in pre-clinical models (57). The carbohydrate GCS-lOO is a pectin derivative that binds to the galectin 3 receptor. Pectin is the methylated ester of poly gal acturonic acid. 

Many drop stabilizers in suspension polymerization are water-miscible polymers. These materials are sometimes called protective colloids. They include naturally occurring substances, such as gelatin and pectin, and a wide range of synthetic polymers such as partially hydrolyzed poly(vinyl acetate)s. Modified natural products such as cellulose ether derivatives are also widely used. Munzer and Trommsdorff provide a detailed list of patented stabilizers [1]. Polymeric stabilizers do not all act in the same way but steric effects are often important [16]. Although transfer of stabilizer molecules from the continuous phase to the drop surfaces can sometimes be fast, the development of drop stability may be slow [17]. That may arise because rearrangement of stabilizer molecules on the drop surface is necessary. Water-miscible polymers are not expected to be good drop stabilizers when the continuous phase is nonaqueous (see Section 5.5). 

The action of a poly-D-galacturonase on a triazinyl derivative of pectin has been investigated, and cncto-poly-D-galacturonase has been used in determining the structure of a polysaccharide of plant origin. ... 

Polysaccharide films and coatings are used to extend the shelf life of fruits, vegetables, seafood, meats and confectionary products by preventing dehydration, oxidation rancidity, surface browning and oil diffusion and in some specific cases can improve the physicochemical, nutritional and sensorial properties of the products. The common poly saccharides used for edible films are starches and their derivatives cellulose and its derivatives seaweed extracts gums pectins and chitosan.
