(also D-ribosyl uracil), an organic substance and nucleoside composed of residues of the pyrimidine uracil and the carbohydrate ribose. Uridine occurs either as a white powder or as long acicular or prismatic crystals. It is soluble in water, acids, and alkalies but insoluble in ether and concentrated ethanol; its molecular weight is 244.2. Uridine is present in all living cells as a constituent of ribonucleic acids. It plays an important role in carbohydrate metabolism, forming part of many coenzymes.

Finally, using the [sup.13]C experimental procedure, we were able to measure metabolites, notably proline and uridine (Figure 2), that would have been otherwise difficult for concentration fit, because they have [sup.1]H NMR spectral peaks that are masked by other larger peaks.
In general, PIWI and AUB show preference for sequences with a 5' Uridine bias mapping antisense to transposons, whereas AGO3 prefers sequences with adenine at the 10th position, mapping sense to transposons [115].
Furthermore, peaks 4, 7, 8, 9, and 10 were identified as uracil, uridine, adenine, guanosine, and adenosine, respectively.
