【 摘 要 】

Oriented samples of the xyloglucan polysaccharide from tamarind seed were examined using X-ray diffraction. Periodicities indexing on a spacing of 2.06 nm were observed along the chain direction. This value is twice that reported for cellulose and is commensurate with four β-1,4-linked glucose residues. Flat, ribbon-like two-fold helical models for the β-1,4-linked polyglucose backbone, with two possible schemes for decoration with xylose and galactose side groups, are proposed.
