Several workers have provided evidence that deacetylation occurs both in vivo and in vitro. Abbott (1942) found that, when N-acetylglycine and sodium benzoate were administered orally to rabbits, the increase in hippuric acid excretion was only slightly less than when the corresponding amount of glycine was given with the benzoate.
