We here show that postprandial 13C
fatty acid tracking is feasible in the human liver using ge-HSQC. Experiments
in two human volunteers revealed that intake of 5 or 7 grams of 13C-labeled
fatty acids resulted in two- or threefold increase in hepatic 13C-enrichment
after 3 hours. It is estimated that 3% of the oral load is stored in the liver
at this time point. The ge-HSQC sequence can be used to reveal the contribution
of dietary fat to the development of hepatic steatosis.
