Acid, acetic glutamic

Kinetic studies on the oxidation of glutamate by manganese(III) in aqueous sulfuric acid, acetic acid, and pyrophosphate suggest different mechanisms for each case. In all cases there is evidence for the involvement of free radicals and in the case of acetic acid and pyrophosphate media a chelated intermediate is postulated. Simultaneous Mn(III)/Mn(IV)-mediated reaction is observed in the oxidation of formaldehyde by...

Nicotinamide functions in the animal body as the active group of two important coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP).These coenzymes are involved in the mechanism of hydrogen transfer in living cells (see Chapter 9) NAD is involved in the oxidative phosphorylation system, the tricyclic acid (TCA) cycle and the metabolism of many molecules, including pyruvate, acetate, (3-hydroxy-butyrate, glycerol, fatty acids and glutamate NADPH is the hydrogen acceptor in the pentose phosphate pathway.
