Abstract

When a diet deficient in one of the following vitamins: thiamine, riboflavin, niacin, pyridoxins pantothenic acid, or folic acid was fed to rats, the activity of the be-taine-homocysteine transmethylase of their livers was found to be higher than that of the livers of rats fed a complete diet. Deficiencies of biotin or choline, on the other hand, caused a slight decrease in the transmethylase activity.
