Primary Structure

The sequence of amino acids in a protein, determining its shape and function.

Amino Acids

Natural substances that merge to create proteins, acting as essential components of life with diverse roles in metabolic processes.

Polypeptide Chain

A sequence of amino acids linked by peptide bonds, forming the primary structure of proteins.
