Common NamePhosphoribosyl pyrophosphate
DescriptionPhosphoribosyl pyrophosphate (PRPP) is a pentosephosphate. The key substance in the biosynthesis of histidine, tryptophan, and purine and pyrimidine nucleotides. It is formed from ribose 5-phosphate by the enzyme ribose-phosphate diphosphokinase. It plays a role in transferring phosphate groups in several reactions. (Wikipedia).
