2010 was used to generate electricity.
Biopolymers are polymers produced by living
organisms; in other words, they are polymeric biomolecules. Since they are
polymers, biopolymers contain monomeric units that are covalently bonded to
form larger structures.
There are three main classes of biopolymers, classified
according to the monomeric units used and the structure of the biopolymer
formed:
1. polynucleotides (RNA and DNA), which are long polymers composed of 13
or more nucleotide monomers;
2. polypeptides, which are short polymers of amino acids; and
3. polysaccharides, which are often linear bonded polymeric carbohydrate
structures
Polymers are everywhere
The way plastics are made is actually a way of imitating nature, which has created a huge
number of polymers.
Cellulose, the basic component of plant cell walls is a polymer, and so are all the
