<p>UDP-N-azidoacetylgalactosamine (UDP-GlcNAz) is an analogue of UDP-GalNAc, bearing an azido group on the N-acyl side chain. It acts as an unnatural substrate for the polypeptide N-R-acetylgalactosaminyltransferases (ppGalNAcTs) which are enzymes that play a role in mucin-type O-linked glycoprotein biosynthesis. UDP-GlcNAz is accepted as a nucleotide-sugar donor, appending an azidosugar onto its native substrates, which can then be detected using azide-reactive chemical probes. The azide group can be detected by the conjugation with phosphine probes via the Staudinger ligation, or alkyne probes via cycloaddition reactions.</p>

Adenosine 5′-phosphosulfate sodium salt has been used quantify pyrophosphate and in enzyme-linked bioluminescence assay for adenosine triphosphate (ATP)

Adenosine is a naturally-occurring organic solvent found in the human body. It has been shown to inhibit fibroid growth and to have an anti-inflammatory effect on the uterus. Adenosine is also a potent endogenous vasodilator, which may be due to its ability to activate adenosine receptors. In addition, it has been demonstrated that adenosine inhibits the synthesis of target enzymes such as collagenase and hyaluronidase. The uptake of adenosine by cells is inhibited by nevirapine, which is an HIV protease inhibitor. This inhibition leads to increased extracellular levels of adenosine, which stimulates phosphorylation of extracellular-regulated kinases (ERKs) and decreases histamine release from mast cells. The ERKs are activated in response to many stimuli including cytokines, growth factors, and stressors such as UV light or heat shock.BR> In vitro studies using human tissue have shown that ad

Transfer of these modified adenosines from one organism to another can lead to changes in their coding and population modifications.
