Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base. Only two 5-carbon sugars are found in nature: ribose and deoxyribose.
Example : monomer of polymer cellulose is beta-Glucose. monomer of simple polimer protein is alpha-amino acid. monomer of PE is ethylene. monomer of Poly( hexamethylene adipamide) is two monomer Hexamethylene diamine and adipic acid. A polymer (/ËpÉlÉ¨mÉr/[2][3]) (Greek poly-, many + -mer, parts) is a large molecule, or macromolecule, composed of many repeated subunits.
