  <name>Isopentenyl pyrophosphate</name>
  <description>Isopentenyl pyrophosphate, IPP or isopentenyl diphosphate, is an intermediate in the HMG-CoA reductase pathway used by organisms in the biosynthesis of terpenes and terpenoids. IPP is formed from Mevalonate-5-pyrophosphate, in a reaction catalyzed by the enzyme mevalonate-5-pyrophosphate decarboxylase. (wikipedia) </description>
