Question

a. Find a biopolymer and briefly describe its chemical composition, whether it would be considered an addition polymer or condensation polymer and its important physical properties. How prevalent is the polymer in nature and what does the organism that produces it use it for? Be sure to include your source.

b. The degradation of some condensation polymers by water is referred to as hydrolysis. Using poly( -decalactone) as an example, draw a proposed mechanism for the acid catalyzed hydrolysis of this polyester.

Explanation / Answer

proteins are important biopolymers, produced in all living organisms. They are condensation polymers formed by bond between acid group(COOH) of one aminoacid and amine group (NH2) of next aminoacid.,thus forming an amide bond.        R-CO-NH2-CO(R)-NH2.,losing a water molecule.                                                 proteins are heat sensitive. they denaturate on heating. They form slightly acidic and basic solutions on varying pH. they are sour to taste and colourless.
