Suitable for manual, auto-analyser and microplate formats.
INTRODUCTION:
In nature, D-xylose occurs mainly in the polysaccharide form as xylan,
arabinoxylan, glucuronoarabinoxylan, xyloglucan and xylogalacturonan.
Mixed linkage D-xylans are also found in certain seaweed species and a
similar polysaccharide is thought to make up the backbone of psyllium
gum. Free D-xylose is found in guava, pears, blackberries, loganberries,
raspberries, aloe vera gel, kelp, echinacea, boswellia, broccoli, spinach,
eggplant, peas, green beans, okra, cabbage and corn. In humans, D-xylose
is used in an absorption test to help diagnose problems that prevent the
small intestine from absorbing nutrients, vitamins and minerals in food.
D-Xylose is normally easily absorbed by the intestine. When problems
with absorption occur, D-xylose is not absorbed and blood and urine
levels are low. A D-xylose test can help to determine the cause of a
child’s failure to gain weight, especially when the child seems to be eating
enough food. If in a polysaccharide, the ratio of D-xylose to other sugars
etc. is known, then the amount of the polysaccharide can be quantitated
from this knowledge plus the determined concentration of D-xylose in
an acid hydrolysate. Xylans are a major portion of the polysaccharides
that could potentially be hydrolysed to fermentable sugar for biofuel
production.
