Proteins consist of one or more of these polypeptide chains. The primary structure of a protein is known as a polypeptide. From the two terminals of the polypeptide chain, N-terminus is where the amino group is free, and the c-terminus is where the carboxyl group is free. Polypeptides are synthesized at ribosomes.The amino acid sequence in the polypeptide chain is determined by the codons in mRNA. Protein. Proteins are one of the most important types of macromolecules in living organisms.he primary structure of a protein is known as a polypeptide.

Primary Structure. The primary structure of polypeptides and proteins is the sequence of amino acids in the polypeptide chain with reference to the locations of any disulfide bonds. The primary structure may be thought of as a complete description of all of the covalent bonding in a polypeptide chain or protein.
