A polypeptide is a string or linear chain of amino acids linked together. Amino acids are the basic building blocks of proteins.[1] A single polypeptide chain might make up the entire primary structure of a simple protein;[2] more complex proteins are formed when two or more polypeptides link together. Each protein is a polymer of amino acids.[3][4]
Polypeptides are made when mRNA is translated, a process involving ribosomes, tRNA and amino acids.
