Common Namealpha-D-ribose 5-phosphate
DescriptionD-Ribose 5-phosphate, also known as R-5-p, belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. D-Ribose 5-phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). A D-Ribose 5-phosphate with an alpha-configuration at anomeric position. D-Ribose 5-phosphate exists in all eukaryotes, ranging from yeast to humans. Within humans, D-ribose 5-phosphate participates in a number of enzymatic reactions. In particular, D-ribose 5-phosphate can be biosynthesized from D-ribulose 5-phosphate; which is mediated by the enzyme ribose-5-phosphate isomerase. In addition, D-ribose 5-phosphate can be biosynthesized from D-ribose through the action of the enzyme ribokinase. In humans, D-ribose 5-phosphate is involved in the metabolic disorder called the ribose-5-phosphate isomerase deficiency pathway.
