Degradation of Biologically Synthesized Lactose labelled with Carbon-14

AN investigation on the labelling of lactose-14C from milk obtained from cows and goats was recently reported by Schambye1. The present communication describes a similar investigation on the distribution of carbon-14 in both hexose moieties of lactose obtained from the milk of a goat employing sodium formate-14C as the lactose precursor (lactose-14C was obtained through the courtesy of Mr. S. Misler, of these Laboratories).
