Intestinal Hydrolysis and Conjugation of a Pesticidal Carbamate in vitro

Abstract
The metabolite 1-[1-14C]naphthyl glucuronide was isolated from mucosal and serosal fluids of everted sacs of rat small intestine incubated in media containing either the insecticide 1-[1-14C]naphthyl N-methylcarbamate (carbaryl) or 1-[1-14C]naphthol. The hydrolysis of carbaryl and conjugation of the liberated naphthol indicated some degree of metabolism by the intestine before absorption.
