The primary structure of proteins, defined by the sequence of amino acids, is crucial for their function and stability. This structure dictates the folding and biological role of proteins, affecting processes from metabolism to immune responses. Alterations in the sequence can lead to diseases like sickle cell anemia or diabetes, making it a key focus in biochemistry and medical research.
