ribonucleotide

 [ri″bo-noo´kle-o-tīd]
a nucleotide in which the purine or pyrimidine base is combined with ribose.

ri·bo·nu·cle·o·tide

(rī'bō-nū'klē-ō-tīd),
A nucleotide (nucleoside phosphate) in which the sugar component is ribose; the major ribonucleotides of RNA are adenylic acid, cytidylic acid, guanylic acid, and uridylic acid.

Interestingly, several scientific findings support the ayurvedic perspective: (1) there are important structural similarities between sweet (T1R2/T1R3) and umami (T1R1/T1R3) taste receptors, both heterodimers, having one subunit in common [160]; (2) mice perceive synergistic umami mixtures (glutamate and ribonucleotide) as tasting sweet [161]; (3) taste cells coexpress the sweet taste and umami taste receptor subunits (all three T1R subunits) [162].
