A polymer is a long chain molecule that is made up of many repeating units (as the name means many parts), called monomers. Polymers can be natural (organic) or synthetic. For example, they are available in plastics such as bottles, toys, vinyl siding, and packaging, and shampoos and other hair care products, contact lenses, food like proteins, starches, gelatin, gum, gluten, fabric, balls, sneakers, and also in our DNA.
Biopolymers are naturally occurring macromolecules that are made up of repeating subunits. This omnipresent family of polymers possesses a huge variety of structural compositions and material properties. Biopolymers like nucleic acid materials such as DNA and RNA are composed of repeated nucleotide subunits. Polypeptides are formed by polymerizing the amino acid subunits, which become proteins by adopting biologically-active conformations.
