Polymers are made up of units
WebA polymer is a large molecule made up of repeating units called monomers. Examples of polymers include proteins, DNA, and plastics such as polyvinyl chloride (PVC) and polystyrene. We will focus here on these plastics, including polyamides, polyesters, and polymers made from alkenes, and the reactions that form them. WebMonomers, or repeated units, make up all polymers. The fundamental structure of proteins is made up of chemical units that are ordered in a precise order. Biological activities are defined by the natural folding of several biopolymers into compact forms. Synthetic polymers have relatively simple and arbitrary structures.

WebDNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).
