CONVERSION OF L-GULONOLACTONE TO L-ASCORBIC ACID; PROPERTIES OF THE MICROSOMAL ENZYME IN RAT LIVER

Abstract
The enzymic reaction was accelerated by alpha, alpha[image]-dipyridyl, versene, 8-hydroxyquinoline, but not by lycorine or diethylbarbiturate. Under anaerobic condition only 2, 6-dichlorophenol indophenol among 5 dyes tested was effective as electron acceptor. Of 12 sugar lactones L-gulono-,L-galactono,D-lyxono-,D-manno-, and D-arabinolactones were utilized as the substrate in the descending order of reaction rate.
