Effect of Dietary Gallic Acid and Pyrogallol on Choline Requirement of Rats

Abstract
Rats fed a low-methionine, low-choline diet containing 1% of gallic acid developed fatty livers. Added choline or methionine prevented the increased liver fat. Pyrogallol, in contrast, did not cause fatty livers. These results are in agreement with the metabolism studies in that gallic acid, but not pyrogallol, is O-methylated in the animal body.
