Evidence for the Occurrence of y-Methylene-aE-oxoglutaric Acid in Groundnut Plants (Arachis hypogaea)

during the course of further work to be reported at a later date. It is certain that there are differences in the effect of diet on different tissues as Long (1953) has found that, although the hexokinase activity of intestinal mucosa is depressed by a lowcarbohydrate diet, that of intestinal muscle is unaffected. In so far as attempts to reproduce the anomalies of carbohydrate metabolism observed in the adult ruminant are concerned, these have been successful and it may be concluded from the similarities between the adult ruminant and the fat-fed nonruminant that many of the apparent abnormalities in the former are due to the peculiar digestive processes of the ruminant rather than to specific hormonal or enzymic differences.
