Physicochemical properties : White or off white or slightly copper blue crystalline powder. It belongs to the ceruloplasmin family with a molecular weight of 140kd and consists of two identical subunits (70kD).It is an oxidoreductase. It catalyzes the reaction of ascorbic acid with oxygen to produce dehydroascorbic acid. Ascorbic acid is an unsaturated polyhydroxy compound, which exists in the form of lactone. The hydrogen on the enol hydroxyl group between the 2 and 3 carbon atoms can be dissociated into H +, so it is acidic.
Purpose: Biochemical research. Elimination of ascorbate. It is a strong reducing agent, which is oxidized and dehydrogenated to dehydroascorbic acid, so it has two forms: oxidation type and reduction type.
