* Polyhydroxoalkanoates and polyesters obtained by enzyme-assisted esterification using lipases.<nowiki/>
* Heparin, heparan sulfate and other glycosaminoglycans and plant glycans.
*Polysaccharides such as cellulose, amylose, chitin and derivatives 
*Natural and non-natural polynucleotides can be successfully obtained by enzyme-assisted synthesis using ligase- or polymerase-based approaches and template-assisted polymerisation.
Human-made biopolymers obtained through approaches that involve genetic engineering or recombinant DNA technology are different from synthetic biopolymers and should be referred to as artificial biopolymer (e.g., artificial protein, artificial polynucleotide, etc.).
