Ascorbic Acid Determination by an Amperometric Ascorbate Oxidase-based Biosensor

The aim of this work is to develop a method for ascorbic acid determination in some fruit juices, by using an ascorbate oxidase-based amperometric enzyme electrode. The enzyme was immobilized on a nylon (Biodyne A) membrane by glutaraldehyde linking. The enzyme-membrane was consecutively attached to the polyethylene membrane of a Clark oxygen electrode, which functioned as transducer. The analy...

On the nature of ascorbic acid oxidase.

In 1937, Stotz, Harrer, and King (1) reported that the activity of several plant juices in catalyzing the aerobic oxidation of ascorbic acid was dependent on their copper content, and such activity was lost upon treatment with substances known to form stable complexes with copper. Since that time, two basically different views have developed concerning the r&e of copper in the aerobic oxidation...

On the Inactivation of Ascorbic Acid Oxidase

1. In the absence of protective agents, highly purified ascorbic acid oxidase is rapidly inactivated during the enzymatic oxidation of ascorbic acid under optimum experimental conditions. This inactivation, called reaction inactivation to distinguish it from the loss in enzyme activity that frequently occurs in diluted solutions of the oxidase prior to the reaction, is indicated by incomplete o...

Localization of ascorbic acid, ascorbic acid oxidase, and glutathione in roots of Cucurbita maxima L.

To understand the function of ascorbic acid (ASC) in root development, the distribution of ASC, ASC oxidase, and glutathione (GSH) were investigated in cells and tissues of the root apex of Cucubita maxima. ASC was regularly distributed in the cytosol of almost all root cells, with the exception of quiescent centre (QC) cells. ASC also occurred at the surface of the nuclear membrane and corresp...
