D-Xylose

D-Xylose is a five-carbon sugar that is absorbed in the small intestine and does not require intraluminal digestion. The protein D-xylose isomerase is an enzyme that catalyzes the conversion of D-xylose to D-xylulose and glucose to fructose by hydrogen-atom transfer. Used extensively by the sweetener industry for the production of high-fructose corn syrup, this protein plays an important economic role in the multi-billion dollar soft-drink market and is the subject of intense research in many other areas.
Xylose is the second most abundant sugar found in hardwood and agricultural residues. Because of its prevalence, xylose utilization is essential in any process for the production of ethanol from these feedstocks. Xylose is relatively easily recovered by acid or enzymatic hydrolysis, but can be fermented to ethanol only by a few naturally-occurring or recombinant microbes.
