The kinetic behaviour and relative reactivities of some carbohydrates (aldoses, amino sugars and methylated sugars) towards platinum(IV) in alkalinemedium have been investigated. The reactions are first order with respect to [substrate] and Pt IV . The rates increase with the increase in OH − . The reactions show pseudo-first-order dependence on OH − . The oxidation rates in alkalinemedium follow the

Abstract The kinetics of oxidation of some aldoses, amino sugars and methylated sugars by tris(pyridine-2-carboxylato)manganese(III) have been studied spectrophotometrically in sodium picolinate–picolinic acid buffer medium. The reactions are first-order with respect to both manganese(III) and sugar concentrations, but independent with respect to sodium picolinate–picolinic acid buffer medium. The

The golden wonder: Various α‐amino acids such as glucosaminic acid, galactosaminic acid, or N‐acetyl‐glucosaminic acid can be obtained from the corresponding glucosaminederivatives (amino sugars). This is achieved through an aqueous oxidation that catalyzed by Au nanoparticles dispersed on basic support under mild reaction conditions in water.
