Engelska Substantiv . alpha helix. alfahelix; Alpha helix definition, the rodlike spatial configuration of many protein molecules in which the polypeptide backbone is stabilized by hydrogen bonds between amino acids in successive helical turns. αヘリックス(Alpha helix)はタンパク質の二次構造の共通モチーフの1つで、バネに似た右巻きらせんの形をしている。 。骨格となるアミノ酸の全てのアミノ基は4残基離れたカルボキシル基と水素結合を形成してい Alpha-helices have 3.6 amino acid residues per turn, ie a helix 36 amino acids long would form 10 turns. The separation of residues along the helix axis is 5.4/ 3.6  The alpha helix is a secondary structure in proteins. This means that it results from the folding of a single amino acid chain. Hydrogen bonds form between  We conclude that under extension and/or compression an α-helix to β-sheet conversion of the coiled-coils occurs in the fibrin clot as a part of forced protein  However, the size and charges of sidechains are also important factors.
