There are three main classes of biopolymers: [[polysaccharide]]s, [[polypeptide]]s, and [[polynucleotide]]s.
In living cells, they may be synthesized by enzyme-mediated processes, such as the formation of DNA catalyzed by [[DNA polymerase]]. The [[protein biosynthesis|synthesis of proteins]] involves multiple enzyme-mediated processes to [[transcription (genetics)|transcribe]] genetic information from the DNA to [[ribonucleic acid|RNA]] and subsequently [[translation (biology)|translate]] that information to synthesize the specified protein from [[amino acid]]s. The protein may be [[posttranslational modification|modified further]] following translation in order to provide appropriate structure and functioning. There are other biopolymers such as [[rubber]], [[suberin]], [[melanin]], and [[lignin]].
