X-ray fiber diffraction patterns of 4.5 and 6.0% iota-carrageenan solutions in the presence of 0.5 and 2.0 M urea subjected to no-heat and heat-treatments. The fibers are almost perpendicular to the incident X-ray beam. The well-resolved Bragg reflections in 6.0% iota-carrageenan in the presence of 0.5 M urea coupled with solution heating indicate ordering among the iota-carrageenan chains.
