Over 500 different amino acids are found in nature, yet only 20 are commonly encoded in the universal genetic code to build proteins. Each of these 20 amino acids is distinct due to a variable side chain, or R-group, attached to a common core structure. This unique structural feature is the key differentiator, influencing the chemical behavior and function of each amino acid within a protein.

Over 500 amino acids exist in nature, yet only 22 are directly coded for in protein synthesis. Understanding what is the classification of amino acids is crucial for comprehending their diverse roles as protein building blocks and their functions in metabolism. This comprehensive guide explores the various ways amino acids are categorized based on their unique properties.
