Abstract
Dehydroascorbic acid reductase, which catalyses the regeneration of ascorbic acid from dehydroascorbic acid, is reported here to occur widely among insects. Due to the reported absence of glutathione peroxidase in insects and the generally low affinity of catalase for hydrogen peroxide, dehydroascorbic acid reductase may play a pivotal role in the elimination of hydrogen peroxide in insects.
