title: [Comparison in genetically obese and normal rats of the uptake and incorporation of labelled lauric acid, oleic acid, and glycerol by the isolated perfused liver].
abstract: Lauric acid, labelled oleic acid and glycerol are perfused in isolated liver of fafa Rats and Wistar Rats previously subjected to fasting. They synthesize TG and PL de novo, though in long time experiments with the normal Rat, the most important method of synthesis is an exchange of AG of the endogenous glycerolipids. However PL are not synthesized with lauric acid. In the livers of fafa Rats the synthesis of TG with oleic acid and glycerol is higher than in livers of Wistar Rats: 16:0 18 : 1 18: 1, 16:0 18: 1 18: 2, 18 : 1 18 :1 18:1, 16 : 0 16 :0 18 : 1 (this TG is not present in liver of Wistar Rat). The hepatic synthesis of PL by the fafa Rat, is less important after 15 min while it is important with Wistar Rats. The synthesized TG with lauric acid (only the TG 12 : 0 12 : 0 12 : 0 with the fafa Rat) are more rapidly oxidized by liver of obese Rat than by liver of normal Rat.
