In enzymology, a L-ascorbate peroxidase (EC 1.11.1.11) is an enzyme that catalyzes the chemical reaction
L-ascorbate + H2O2Thus, the two substrates of this enzyme are L-ascorbate and H2O2, whereas its two products are dehydroascorbate and H2O.
This enzyme belongs to the family of oxidoreductases, specifically those acting on a peroxide as acceptor (peroxidases). The systematic name of this enzyme class is L-ascorbate:hydrogen-peroxide oxidoreductase. Other names in common use include L-ascorbic acid peroxidase, L-ascorbic acid-specific peroxidase, ascorbate peroxidase, and ascorbic acid peroxidase. This enzyme participates in ascorbate and aldarate metabolism.
