Abstract
IT has been shown [above] that the enzyme preparation from acetone-dry small intestines of animals can synthesize a comparatively small amount of ascorbic acid. The probable explanation is that the enzyme is denatured by acetone treatment. This is suggested by the fact that the enzyme preparation obtained by extracting the fresh jejunum of the goat and guinea pig shows synthesis of a greater amount of ascorbic acid. Four hours incubation of the enzyme extract with glucose at pH 6·5 and in presence of added manganese produces the following results.
