Question

what is polymer and monomer?

Answer 1

A chemical reaction bonding monomers together to make a polymer is called polymerization. Some polymers are naturaland made by organisms. Proteins have polypeptide molecules, which are naturalpolymers made from various amino acid monomer units.
A polymer is a very large, chain-like molecule made up of monomers, which are small molecules. It can be naturally occurring or synthetic. ... Since poly- means "many," a polymer means "many parts."
A monomer is a molecule that "can undergo polymerization thereby contributing constitutional units to the essential structure of a macromolecule". Large numbers of monomers combine to form polymers in a process called polymerization.
