11. Xylans are polysaccharides made from units of xylose ( a pentose sugar ). 12. This enzyme participates in pentose and glucuronate interconversions and ascorbate and aldarate metabolism. 13. This enzyme participates in pentose and glucuronate interconversions and starch and sucrose metabolism. 14. Three phosphate groups are attached at the 52 carbon atom of the pentose sugar. 15. Galactonate is metabolized by the pentose phosphate pathway, and is not considered toxic. 16. This enzyme participates in pentose and glucuronate interconversions. 17. Furthermore, it is a participant in and a product of the pentose phosphate pathway. 18. This enzyme participates in pentose phosphate pathway. 19. The protein functions by blocking glycolysis and directing the pathway into the pentose phosphate shunt. 20. In the pentose , the carbon closest to the carbonyl group is labeled C-1.
