preparing unenriched and [1-13C]-enriched 5-deoxy- and 5-O-methyl-pentoses in the D or L configuration. The 1H-n.m.r. spectra of these compounds have been interpreted, and the 13C-n.m.r. spectra assigned with the aid of 2-D 13C-1H chemical-shift correlation spectroscopy. Tautomeric forms (furanoses, hydrate, and aldehyde) in solution in 2H2O have been quantified with the aid of [1-13C]-enriched derivatives
The embodiments described herein provide a method for improving bowel health by increasing short chain fatty acid concentration in the colon of a mammal including administering to the mammal a composition having from about 0.1 grams to about 50 grams of a treated bran product. After administration, the treated bran product results in an increased short chain fatty acid production during fermentation in the colon as compared to untreated bran fermented in the colon.
