Notes:
The diffuse x-ray diffraction patterns of agarose gels are compatible with both the “chicken-wire” gel model consisting of associated double-helix chain conformations and a network of more extended, but unentwined helices. Preference f or the double-helix model has largely rested on an early interpretation of optical rotation data. Applying a recent, less empirical, chiroptical model of saccharide rotation, we confirm the earlier analysis by concluding that the rotation observed in the gel can be satisfactorily accounted for in terms of wide-diameter agarose helices, capable of intertwining. In addition, we have found that the extended helices found in dried sols do not yield the observed gel rotations. © 1995 John Wiley & Sons, Inc.
