The molecular weight of lysozyme has been redetermined by the ultracentrifuge as 14,100 ± 500. The molecule appears to be a stubby prolate ellipsoid of rotation, with a maximum length of 90 Å and a minimum equatorial diameter of about 18 Å depending on the degree of hydration assumed. Alternative possibilities of chain orientation within this shape are discussed assuming that the chains are coiled in Pauling–Corey helices.
