title: [Utilization of glucose, valine, glycerin and palmitic acid by energy and anabolic pathways of metabolism in rats].
abstract: Possibility of evaluation of nutrients use by energy and anabolic ways by measurement in blood of radioactivity of water formed from labelled by tritium precursors was studied. The experiment was made on rats, which consecutively with interval 1.5-2 weeks were given intravenous indicative amount of 3H2(2,3)-valine, 1-14C-glucose, 6-3H-glucose, 3H2(1,3)-glycerin and 3H2(9,10)-palmitic acid. Half-time of glucose in blood was 46 min, glycerin--16 min, valine and palmitic acid--24 min. Plastic and energy characteristics of these substances were studied. The proposed approach to the evaluation of plastic and energy functions of nutrients can be useful for development of specialized products for enteral and parenteral feeding.
