Alpha Helices

Alpha helices are a common structural element in proteins, where the chain of amino acids folds into a tight, spiral shape like a spring. This regular coiled structure is stabilized by hydrogen bonds between parts of the chain, giving the protein stability and flexibility. Think of it as a tightly wound coil that helps proteins perform specific functions, such as building structures or facilitating chemical reactions. Alpha helices are fundamental to the protein's three-dimensional shape, influencing how the protein interacts with other molecules in the body.
