Apart from its well-known role in the prevention of scurvy, ascorbic acid (1, vitamin C) has been implicated in a number of diverse biological processes. For example, the monooxygenase, dopamine fl-hydroxylase, which catalyzes the hydroxylation of 3,4-dihydroxyphenylethylamine (dopamine) to noradren
