(a) SAXS pattern from collagen. (b) Molecular model that
explains the observed pattern in terms of the electron density
variation caused by the overlapping and gap regions in the staggered
arrangement of the collagen triple helices. (c) A typical SAXS pattern
from a semicrystalline polymer (nylon 6) with folded chains. (d) A
schematic of the titled lamellar arrangement that accounts for the
observed pattern. (Source: Courtesy of S. Rugmai, Synchrotron
