Alpha Helix

An alpha helix is a common structural feature in proteins, resembling a right-handed spiral or coil. It is formed when a chain of amino acids twists into this shape, stabilized by hydrogen bonds between the backbone of the protein. This helical structure helps proteins maintain their shape and stability, which is crucial for their function in biological processes. Alpha helices are found in many proteins, playing roles in everything from enzymes to structural components in cells, and are essential to understanding how proteins work in living organisms.
