Answer:
This is a picture of an aminoacid chain
Step-by-step explanation:
In an amino acid chain all amino acids ( for example GLY, VAL, or ARG) are linked by peptide bonds. Long chains, also called polymers, of amino acids are called proteins. The enlarged photo is an example of a structure of an amino acid. They have an amine (-NH2) and carboxyl (-COOH) functional group, along with a side chain (R group), specific to each amino acid.
