Molecules are a form of compound, but yes depending on the molecule they can be broken down into other compounds.
The smaller molecules that make up polymers are called monomers.
Proteins are made from long chains of smaller molecules called amino acids. Amino acids are biologically important organic compounds that are composed of amine and carboxylic acid.
The phenomena of formation of large carbon compounds by the addition of small molecules is called polymerization and the molecules are come under macromolecules as they possess molecular weight several to hundred thousands
Smaller molecules called amino acids make protein molecules.
These are called polymers. They are made by a large number of monomers bond together. These polymers are macro molecules.
