Monomers are the building blocks that make up nucleic acid. Also known as nucleotides, they are composed of a five-carbon sugar, a nitrogenous base and a phosphate group.
sugar is the monomer of carbon hydrates. for example, glucose is the monomer of cellulose. lipid are not multimer, lipid are bound together via non-covalent interaction and solvation entropy. The monomer of the protein is amino acid. The monomer of the nucleic acid is single nucleotide.
