WebAug 7, 2024 · The first two protein structure to be determined, myoglobin and hemoglobin, consists mainly of alpha helices. Researchers were surprised to see how random the orientation of helices seemed to be. Other all alpha-helical proteins show bundles of nearly parallel (or antiparallel) helices (e.g. bacterial cytochrome c' 1e83 ).
