Abstract:
Lactose intolerance is a pathology caused by lactase enzyme deficiency, usually produced in the intestinal cells provoking symptoms as abdominal pain, bloating, diarrhea, gas and nausea. Gaxilose, 4-O-β-D galactopyranosyl-d-xylose, is used as a diagnostic drug for a non-invasive method for hypolactasia diagnosis. To date, no definitive guide for identifying gaxilose and distinguishing between crystalline forms is available. Data have been collected from a number of different analytical techniques in order to provide a full characterization of the compound and a simple method to discriminate between two solid forms.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...
