1. This carboxylic, acidic side group is made of xylose and arabidose. 2. It is a C'- 2 carbon epimer of the sugar Xylose . 3. Xylans are polysaccharides made from units of xylose ( a pentose sugar ). 4. This enzyme catalyze the direct formation of D-xylulose from D-xylose . 5. The mice apparently can digest the xylose and they eat large quantities of the pollen. 6. Humans must obtain xylose from their diet. 7. Ustilaginomycotina has a distinctive cell wall composition consistent of mostly glucose and absence of xylose . 8. Sorbitol, xylose and sucrose proved to be the best carbon sources for tabtoxin production. 9. In addition to cellulose, ?-glucosidases can cleave xylose , mannose and galactose. 10. The large and complex glycans that modify proteoglycans are initiated by addition of xylose to serine.
