L-ascorbate + ferricytochrome b₅ $rightleftharpoons$ monodehydroascorbate + ferrocytochrome b₅ + H⁺

Thus, the two substrates of this enzyme are L-ascorbate and ferricytochrome b5, whereas its 3 products are monodehydroascorbate, ferrocytochrome b5, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with a cytochrome as acceptor. The systematic name of this enzyme class is L-ascorbate:ferricytochrome-b5 oxidoreductase. This enzyme is also called ascorbate-cytochrome b5 reductase.
