Verified step by step guidance

Understand the basic building blocks of proteins, which are amino acids. Amino acids link together through peptide bonds to form chains.

Recognize that these chains of amino acids can vary in length. Short chains are typically referred to as peptides.

Learn that when a chain of amino acids exceeds a certain length, it is referred to as a polypeptide. This is generally when the chain has more than 50 amino acids.

Differentiate between the terms: a single amino acid is just an amino acid, a short chain is a peptide, and a longer chain (more than 50 amino acids) is a polypeptide.

Conclude that the term used for an amino acid chain with greater than 50 covalently linked amino acids is 'polypeptide'.
