The sugar splits up in the metabolism to C2 building blocks, which are converted, over several steps, to C4 monomers. Question 17. Since the beginning of the 20th century, hundreds of polymers have been synthesized. Polymers make up many of the materials in living organisms, and they constitute the basis of certain minerals and human-made materials, such as paper and plastics. Note 2: Biochemists are now capable of synthesizing copies of biopolymers that should be named Synthetic biopolymer to make a distinction with true biopolymers.. The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. [2][3] Biomer L is the trade name of PHBV from Biomer. PHBV is known as Poly(3-hydroxybutyrate-co-3-hydroxyvalerate. It is a thermoplastic linear aliphatic polyester. Production of Materials‎ > ‎2. Short-chain PHAs, such as PHB, are made of smaller monomers. Start studying Polymers. The most studied biopolymers in real liquid environment are the polyhydroxyalkanoates such as PHB and PHBV and several polyesters such as PCL and PLA . Major difference can be identified by their structure. In proteins, primary structure consists of specific chemical composition and all units are arranged in sequence. PHA’s can be produced with a range of different monomers, by adjusting the feedstock and bacterial strains, resulting in a variety of co-polyesters with various properties. Medium-chain PHAs, such as poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH), are made of larger ones. PHBV is used in speciality packaging, orthopedic devices and in controlled release of drugs. Properties range from elastomeric to resins as stiff and tough as nylon 6 or polycarbonate. Natural Polymers: They occur naturally and are found in plants and animals.
