As pentose sugars are mainly derived from ribonucleotides, in particular inosine-5'monophosphate (IMP), 2-methyl-3-furanthiol and its disulfide can be formed from reaction of IMP or ribose with cysteine or cystine or glutathione or by thiamine degradation (Figure 2; Shi and Ho, 1994; Melton, 1999).

The enzyme thiopurine methyltransferase (TPMT) facilitates formation of 6-methylmercaptopurine ribonucleotides (6-MMPN), which are inactive metabolites and may be responsible for some toxicities of AZA.
The cDNA products were incubated with T7 RNA polymerase, and biotinylated ribonucleotides using an in vitro transcription kit (Enzo Diagnostics Inc.

Two lines of all-natural flavors have been developed for meats and meat products: "Cuisine" flavors contain no HVP or added taste enhancers such as ribonucleotides and MSG.
Structurally, GSH is made up of a tripeptide, consisting of glutamic acid, cysteine and glycine residues, while functionally it participates in the detoxification of [alpha]-oxoaldehydes, the reduction of ribonucleotides to deoxyribonucleotides, the regulation of both protein and gene expression, through thiol: disulfide exchange reactions, (14) and as a component of the glyoxalase system, which functions in the control of cellular growth.
LNA probes are ribonucleotides with a methylene bridge that connects the 2' oxygen of ribose with the 4' carbon.
3-5 mL double-stranded cDNA was mixed gently with 4 mL each of 10x high-yield reaction buffer, 10x biotin-labeled ribonucleotides, 10x DTT, 10x RNase inhibitor mix, and 10x T7 RNA polymerase provided by the kit and incubated at 37[degrees]C for 4-5 hr, with gentle mixing every 30 min.
