Abstract
One or two hours after intraperitoneal injection of trace amounts of glucose-1-H3 and glucose-1-C14 obese-hyperglycemic mice of the Bar Harbor strain converted five to ten times as much of both radioisotopes to total fatty acids of the liver and two to four times as much to total fatty acids of the remaining carcass as their lean siblings. The obese mice generally oxidized glucose-1-C14 to C14O2 and glucose-1-H3 to H3OH at rates equal to those of the lean mice. At 2 hr, 40–45% of the glucose-C14 had been converted to C14O2 and 75–80% of the glucose-1-H3 to H3OH. The maximum conversion of tritium to liver fatty acids was about .4% of the dose at 1 hr and of C14 about .25% of the dose at 1 hr, while for the carcass fatty acids the highest conversion were at 2 hr with about 2.0% of the dose of glucose-1-H3 and 1.8% of the dose of glucose-1-C14.Keywords
