The reaction at each of these pH was studied at five different temperatures whereby specific rates, energies of activation and entropy activation values were determined. Further, the variation in the nucleophilicity of caffeine at these pH values was estimated in terms of its reduction propensity ...
levels of caffeine, due to inhibition of caffeine oxidation, a reaction catalysed by one or more hydrocarbon-inducible isoenzymes of P450. Furafylline has either very little or no effect on human monooxygenase activities catalysed by other isoenzymes of P450, including P4501ID1, P4501IC, P450...

A clinical investigation was carried out to evaluate how ritlecitinib altered the pharmacokinetic processes of caffeine, a substrate of the CYP1A2 enzyme.In this open-label, single-arm, single-center, fixed-sequence study, healthy volunteers were given a single 100-milligram dose of caffeine on...
There are a number of different ways in which coffee’s aroma compounds are created, but they’re all commonly produced as a consequence of the roasting process. The Maillard reaction, the complexities of which werediscussed on the site recently, is a big contributor here, the reaction between...

better materials. By focusing on the liquid layer rather than the surface of the material, “that’s kind of a whole different way of looking at this problem, and opens up a whole new dimension, a whole new axis along which we can change things and optimize some of these reaction...
