A one-pot reaction sequence is described in which the addition of one compound allowed switching between simultaneously occurring oxidation and reduction reactions.

Oxidation-reduction reactions in chloroplasts were first 01 served when Hill (1) discovered photolysis by isolated chloro plasts. In the Hill reaction electron transport proceeds from water to the artificial oxidant which can be any one of a number of compounds (24). A cyclic series of oxidation-reduction reactions is postulated as the basis for photosynthetic phosphorylation by spinach chlorop...

MicroElectroMechanical System (MEMS) devices often require low-temperature, fluxless soldering techniques due to their high temperature sensitivity and the performance requirements of specific components. While seeking the development of a soldering technology using pure indium, the major focus of this study is to assess the thermodynamics and kinetics of indium oxidation at various solder refl...

Distinctions between primary and secondary are defined, and the basic building blocks used in the biosynthesis of secondary natural products are introduced. The chemistry underlying how these building blocks are assembled in nature is described, subdivided according to chemical mechanism, including alkylation reactions, Wagner–Meerwein rearrangements, aldol and Claisen reactions, Schiff base fo...

The Division of Biochemistry, Faculty of Chemistry, Opole University for more than 10 years has been involved in analysis of reactions catalysed by tyrosinase (monophenol oxidoreductase, L-dopa:O2, EC 1.14.18.1). This is a key enzyme in melanization process that catalyses its two first reactions: o-hydroxylation of tyrosine to 3,4-dihydroxyphenylalanine (DOPA) and oxidation of dopa to dopaquino...

Chicken liver xanthine dehydrogenase can be partially reduced by either xanthine or NADH. Reduction to approximately the 2-electron-reduced level occurs with NADH, and reduction beyond the 2-electron level occurs with xanthine. In both cases, the reaction is triphasic. The first and third phases are dependent on reductant concentration, whereas the second phase is not. Oxidation of fully (6-ele...
