More than half dry weight of a cell is of protein. We report the discovery that heat can be used to reversibly cycle a protein between its polymeric and monomeric states. A monomer is a single molecule that can be joined together with other same molecules to form a polymer. Biological polymers are large molecules composed of many smaller molecules linked together. If R- group is not equivalent to ‘H’ the a-carbon atom is known as asymmetric; a-amino acids are chiral or optically active compounds. Of these, macromolecules, carbohydrates, proteins and nucleic acids are considered polymers while lipids are not. The unit constituent of protein in amino acid. Bjerrum in 1923 proposed the term zwitter ion, derived from German word ‘zwitter’ meaning hybrid: The fundamental structural unit of protein is a-amino acid. Polymer. A polymer (; Greek poly-, "many" + -mer, "part") is a large molecule, or macromolecule, composed of many repeated subunits. Why Are Proteins Considered Polymers When Lipids Are Not. A polymer is made up of multiple sub units tied together. Proteins, chain molecules of amino acids, behave in ways which are similar to each other yet quite distinct from standard compact polymers. Normally you can just refer to the polymers just as proteins, but if you want to be specific, you can say polypeptide, thereby excluding amino acids, dipeptides, and oligopeptides. Since they come from chains of monomers, proteins are also known as polymers.To qualify as proteins, amino acid chains must contain more than about 30 individual acids. Biopolymers are polymers consisting of organic monomers found in living organisms. Disclaimer 9.
