    three-dimensional shape of a protein determining its function

    Protein structure refers to the three-dimensional arrangement of atoms within a protein molecule. This structure is crucial because it determines the protein's function in biological processes. Proteins fold into specific shapes, which can be described at four levels: primary (sequence of amino acids), secondary (local folding into alpha-helices and beta-sheets), tertiary (overall 3D shape), and quaternary (assembly of multiple protein subunits). Proper folding is essential for the protein's activity, and misfolding can lead to diseases.
