Biopolymers biological agents used

Synthetic examples include the poly(meth)acrylates used as flocculating agents for water purification. Biological examples are the proteins, nucleic acids, and pectins. Chemically modified biopolymers of this class are carboxymethyl cellulose and the lignin sulfonates. Polyelectrolytes with cationic and anionic substituents in the same macromolecule are called polyampholytes. [Pg.450]

Unfortunately, these agents are extremely toxic, so that they cannot be used in every case. In the same paper, the resistance of polyacrylamide to bacterial degradation was reported. In order to combine the stability of the all carbon vinyl-chain with the bulkiness (chain extension) and the intermolecular interactions known from biopolymers, a group of the vinyl-saccharides have been synthesized. Another kind of biological aging is found in in enzymatic decomposition reactions, e.g., the cracking of starch to a-g1ucose with a-amylose. [Pg.7]
