Hepatic glycogen formation by direct uptake of glucose following oral glucose loading in man
Abstract:
The extent of direct uptake of glucose into hepatic glycogen following oral glucose loading in man is determined by mobilizing newly formed glycogen with a glucagon infusion in the immediately postabsorptive period. The amount of glucose flushed from liver glycogen is measured by using "out-of-steady-state" tracer turnover techniques. Following a 93 +/- 1 g load of glucose, at most 7.7 +/- 1 g of ingested glucose is recovered from glycogen. If the unlabelled glucose pool is taken into account, at most 10 g of available glucose can be said to be taken up directly into hepatic glycogen during the absorption of the glucose load.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

In addition to accelerating glucose uptake and utilization, insulin has...
Metabolic States of the Body: The Absorptive State
Metabolic States of the Body: The Postabsorptive State
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...
