Alpha helical coiled-coil, illustration. An alpha helix is a secondary structure formed from a protein's polypeptide chain of amino acids. The helical structure arises when the carbonyl group (a carbon atom double bonded to an oxygen atom) of one amino acid forms a hydrogen bond with the amino hydrogen atom of an amino acid four places down the chain. An alpha helical coiled-coil consists of two parallel alpha helices. | |
