Proteins, polysaccharides and nucleic acids are polymeric organic molecules built out of a very large number of repeating sub-units. The nucleic acids, double-helical DNA and single-stranded RNA are built
Monomers and Polymers. Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. All monomers have the capacity to form chemical bonds to at least two other monomer molecules. monomers.Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.a polymer. Homopolymers are polymers made by joining together monomers of the same chemical composition or structure.eteropolymers are polymers composed of more than one kind of monomer. a polymer consisting of more than one type of monomer. Artificial Polymers and Special Properties. One of the first humans to discover, and make, an artificial polymer, was the German chemist Hans von Pechmann.
