INTRODUCTION TO PROTEIN STRUCTURE
Proteins are among the most important biomolecules present in living organisms. They perform numerous functions such as enzymatic catalysis, transport, defense, hormonal regulation, muscle contraction, and structural support. The biological activity of a protein depends directly upon its three-dimensional structure.
A protein is made up of amino acids linked together by peptide bonds forming long chains called polypeptides. These polypeptide chains fold into specific structures that determine their functions.
