Structural information obtainable by wide- and small-angle X-ray scattering. (a) The radial position of the WAXS reflection can be used to determine average collagen intermolecular spacing. (b) The WAXS azimuthal intensity profile yields information on collagen orientation. The length of a particular vector in the resulting polar graph is indicative of the number of fibrils preferentially aligned in the vector direction. The radial position of SAXS reflections indicates the average collagen fibril (c) diameter, and (d) spacing.
