: '''Condensation polymerisation''' [[Chemical Reaction|reaction]]s are called '''condensation''' [[Chemical Reaction|reactions]] because they usually [[product|produce]] [[Water]], but they may also [[Product|produce]] other small [[molecule]]s such as HCl.

: '''Condensation polymerisation''' [[Chemical Reaction|reaction]]s happen commonly in biological [[organism]]s.

====Forming Polyesters====

: '''Condensation polymerisation''' [[Chemical Reaction|reactions]] which [[product|produce]] [[Water]] can happen when one end of a [[molecule]] carries an -OH [[Functional Group|group]] while the other end carries a -COOH [[Functional Group|group]]. These [[Chemical Reaction|react]] together joining the [[molecule]]s forming a [[Polyester]].

====Forming Proteins====

: Each [[Amino Acid]] has an NH₂ [[Functional Group|group]] which acts as a [[base]] and an -COOH [[Functional Group|group]] which acts as an [[acid]]. These [[Functional Group|functional groups]] [[Chemical Reaction|react]] to [[Product|produce]] [[Polypeptide]]s and [[Water]].

n x Peptides → Polypeptide + Water
