^*Three rats weighing 427 ± 27 g were housed individually in metabolic cages and fed Purina Basal Diet 5755 for 3 d. Pinitol, 51.5 μmol (10 mg), was given orally with urine and stools collected for the following 2 d, which were analyzed for total DCI. Then 25 nmol [²H₆]DCI was given orally, followed by an additional 2 d of urine and stool collection. No [²H₆]DCI was detectable before isotope administration.
