The monomer unit of proteins is :
Amino acid
Proteins are polymers (polypeptides) built from amino acids joined to one another by peptide bonds; about 20 different amino acids occur in natural proteins.
Each amino acid has an amino group, a carboxyl group and a side chain attached to a central carbon atom, and the sequence of amino acids decides the shape and function of the protein.
Nucleotides are the monomers of nucleic acids (DNA and RNA), glucose is the monomer of starch, glycogen and cellulose, and fatty acids are building blocks of fats (lipids).
Hence, Amino acid.

In eukaryotic cells, covalently attached lipids help to anchor some water soluble proteins to the plasma membrane. One group of cytosolic proteins are anchored to the cytosolic face of membrane by a fatty acyl group (e.g. myristate or palmitate). These groups are generally covalently attached to which amino acids present at the N‐terminus of the polypeptide chain?
