Bio polymers and Biodegradable polymers
Bio polymers Biopolymers are a special class of polymers found in nature, starch, protein and peptides. DNA and RNA are all examples of biopolymers, in which monomer unit, respectively are sugars, amino acids and nucleic acids. A major difference between biopolymers and polymers can be found in their structures. Bio polymers inherently have a well defined structure. Many biopolymers spontaneously "Fold" in to characteristic shapes, which determine their biological functions and depend in a complicated way on their primary structures. Structural biology is the study of the shapes of biopolymers. In contrast most synthetic structures have much simpler and mere random or statistic structures. Another important difference is the lack of a molecular mass distribution in most biopolymers. As their synthesis is controlled by a template direct process in all bio polymers are alike, they all contain the same sequence and numbers of monomers and thus all have the same mass. This p...
