Condensation+Polymerisation

 * A condensation polymerization occurs when a [|polymer] is formed from a reaction that leaves behind a small molecule, often water. The formation of peptide bonds in proteins is an example of a condensation polymerization. In this case, an [|amine]reacts with a [|carboxcylic acid] to form an [|amide] bond. Glycine is the simplest amino acid: the reaction below shows the reaction between two glycine molecules to form a glycine dimer. ||
 * the atoms in the red box drop away to form the water molecule on the right. This is the reaction that is used for all amino acids in the formation of proteins and is fundamental to life as we know it.A common industrial condensation polymerization is the formation of Dacron, a polyester. In this case an [|alcohol] (in green) reacts with a [|carboxcylic acid] (in red)to form an [|ester] bond (in blue) and a water molecule drops away.
