Popis: | Obesity is associated with increased hepatic glycogen content. In vivo and in vitro data suggest that plasma free fatty acids (FFA) may cause this increase. In this study we investigated the effect of physiological plasma FFA levels on hepatic glycogen metabolism by studying intrahepatic glucose pathways in lean and obese subjects. Six lean and 6 obese males were studied twice during a 16- to 22-hour fast, once with and once without acipimox, an inhibitor of lipolysis. Intrahepatic glucose fluxes were measured by infusion of [2-C-13(1)]glycerol, [1-H-2(1)]galactose, and [U-C-13(6)]glucose. Acetaminophen was administered as a glucuronate probe. In both lean and obese control studies, plasma FFA levels increased progressively, whereas acipimox completely suppressed plasma FFA levels for the whole study period. In lean males glycogenolysis did not change in the acipimox study, but decreased in the control study (P |
