Xylan spectroscopy and spectrophotometry
Biotechnology Techniques, 1990An iodine-iodide reagent containing saturated calcium chloride was used for quantitation of larchwood xylan in solution and for improved visualization of xylanase activity on solid media. This spectroscopic methodology is applicable to hemicelluloses from other sources and can differentiate hemicelluloses from other polysaccharides such as amylose ...

Xylan and Xylan Derivatives – Basis of Functional Polymers for the Future
2011This review highlights xylan and xylan derivatives. It depicts the occurrence and structural diversity of the biopolymer, followed by a presentation of different ways of isolation from biomass. The determination of characteristics, i.e., molecular weight, interaction with other polysaccharides, thermal behaviour, and the biological activity of xylan ...

CRYSTALLINE XYLANS FROM STRAWS
Canadian Journal of Chemistry, 1953Hemicelluloses, extracted from barley, flax, oat, rye, and wheat straw holo-celluloses, were composed predominantly of anhydro-D-xylose units, with small amounts of L-arabinose and D-glucuronic acid. The hemicelluloses had degrees of polymerization ranging from 55 for oat to 185 for rye and were shown to be linear polysaccharides.
