In enzymology, a L-ascorbate oxidase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are L-ascorbate and O2, whereas its two products are dehydroascorbate and H2O.This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with oxygen as acceptor.
