Studies on the Triple Helical Structure of β-ᴅ-1,3 Xylan

  • M. A. Haleem and Salma Qamruddin

Abstract

The triple helical structure of β-ᴅ-1,3 xylan is described. The 0-value is reduced to 3.447 from 4.417 by number of small modifications to the structure including variations in the position of water molecule. The R-value after the refinement is found to be 0.37. The present calculations indicate that water is certainly involved with the structure possibly in a more complicated way as proposed by earlier workers. The present work supports the previous finding of Haleem and Parker that the molecule should be 8% smaller in radius.
