Proteins are the natural polymers that play a vital role in life processes. 15. list the monomers and polymers of carbohydrates lipids proteins and nucleic acids, When different elements combine through chemical reactions, they form compounds. We then examined capture and separation of particular proteins from a protein mixture by cooling-induced phase separation. Match. The polymer polyethylene glycol (PEG) is the preferred coating for nanoparticles for biomedical applications because of its ability to reduce protein adsorption, but in the last few years a dramatic increase of allergic reactions triggered by this polymer have been observed. So let us now look into the classification of polymers. Polymers of proteins are formed through a series of reactions in which bonds are formed and in some cases, folding occurs as a result of the type of bonding. Let us have a look at your work and suggest how to improve it! Proteins make more than 50% of dry weight of cells and are present in large amounts than any other biomolecule. All enzymes are also proteins, which are molecules that are necessary for cellular reactions to occur. Learn. ELPs are intrinsically disordered protein polymers derived from the hydrophobic domain of the human extracellular matrix protein tropoelastin. Thus, proteins are the polymers of amino acids. Digestive enzymes 3. Polymers are large molecules made up of many smaller subunits. The wide array of configurations and bonding patterns result in vast molecular diversity. Keywords:Proteins, polymers, protein-polymer conjugates, smart-polymers, therapeutic proteins, toxic. The secondary structure of proteins depends largely on the interaction of peptide bonds with water through hydrogen bonds. Not only inanimate objects, many proteins in your body are polymers. One amino acid is a monomer. Because they are poly-mers. Furthermore, some of the polymers allows A large molecule that is composed of two or more monomers is called a polymer. Key Concepts: Terms in this set (38) Nearly every biochemical process that takes place in the living cell requires a _____ to catalyze a chemical reaction, regulate a biological response, or provide structural support to the cell.
