Alpha-helical proteins

Alpha-helical proteins are a type of protein structure characterized by a coiled, spiral shape called an alpha helix. This helix forms when the protein's chain of amino acids folds in a specific way, stabilized by hydrogen bonds. The alpha helix is a common structural element that helps proteins maintain their shape and perform their functions, such as enabling enzymes to catalyze reactions or allowing structural support in cells. Think of it as a tightly wound spiral staircase within the protein that provides stability and flexibility essential for biological activity.
