5-Diphosphomevalonic acid (CAS: 1492-08-6) is a metabolic intermediate in the mevalonate pathway, catalyzed by the enzyme phosphomevalonate kinase from 5-phosphomevalonate (Wikipedia).

Alpha-D-ribose 1-methylphosphonate 5-phosphate is a ribose monophosphate that is alpha-D-ribose having a monophosphate group at position 5 as well as a methylphosphonate group at position 1. It is a ribose monophosphate and an organic phosphonate. It is a conjugate acid of an alpha-D-ribose 1-methylphosphonate 5-phosphate(3-). alpha-D-Ribose 1-methylphosphonate 5-phosphate is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).

(R)-Mevalonic acid-5-pyrophosphate (mevalonate 5-diphosphate) is a directly synthesized product of mevalonate phosphate that is essential for cell proliferation. (PMID 2211719). It is a substrate for mevalonate-5-diphosphate decarboxylase, the third enzyme involved in the biosynthesis of cholesterol from mevalonic acid. This enzyme catalyzes the reaction of mevalonate 5-diphosphate (MVADP) with ATP to produce isopentenyl diphosphate, ADP, CO2, and inorganic phosphate. The overall reaction involves an anti elimination of the tertiary hydroxyl and carboxyl groups. This metabolite participates both in the biosynthesis of cholesterol and fatty acid mechanism, through which interpathway regulation could take place between the cholesterol and FA cascades. (PMID 8769113 ).
