Protein is a substance composed of amino acid monomers
Further explanation
Polymers are large molecules formed from repetitive smaller molecules called monomers
The polymer itself is formed through an addition or condensation reaction
Protein is a form of polymer that is formed naturally. Proteins are formed from amino acids (carboxylic compounds with amine groups).
Amino acids combine with other amino acids to form peptides. Proteins are formed from polymerization of peptides, so proteins are also called copolymers because they are formed from polymers from various amino acids
While salt is the result of a reaction between acids and bases so that salt is an ion compound because it consists of cations from bases and anions from acids
For ethanol and propane both are carbon compounds where ethanol is an alcohol which has a -OH functional group (C₃H₈O) and propane is a hydrocarbon compound (consisting of hydrogen and carbon) with a single bond (C₃H₈)
