L-ascorbate peroxidase

In enzymology, a L-ascorbate peroxidase (EC number|1.11.1.11) is an enzyme that catalyzes the chemical reaction

:L-ascorbate + H₂O₂ $ightleftharpoons$ dehydroascorbate + 2 H₂O

Thus, 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.
