[Effect of moderate amounts of food saccharose on glucose and fructose metabolism in the liver of rats].

Thirty-six male Wistar rats received rations containing 0, 5 or 15% sucrose during 40 days. Significant changes were recorded in the utilization of 6-3H-glucose for the synthesis of lipids and glycogen of the liver. The effect of sucrose feeding on hepatic lipid metabolism depended on the sucrose level: 6-3H-glucose incorporation into liver lipids increased after feeding with the ration containing 5% sucrose, while it was suppressed by 15% sucrose. 6-3H-glucose incorporation into glycogen of the liver was suppressed by both sucrose levels in the ration. U-14C-fructose incorporation into liver glycogen and lipids was not affected by sucrose feeding.
