Abstract

The uptake, release, and oxidation of individual free fatty acids (FFA) in the human forearm were studied during a 60-min exercise period. Muscular uptake of FFA rose with the arterial concentration. The muscle showed a slight preference for linoleic and oleic acid compared to palmitic acid. The forearm RQ indicated a constant fat oxidation during the period of exercise. The uptake of FFA covered about 50 per cent of the fat oxidation. On the average 60 per cent of the muscular FFA-14C uptake was oxidized to 14CO2. The remaining radioactivity left the muscle as water-soluble metabolite(s). β-Hydroxybutyrate leaving the muscle was shown to be labeled. No release of glycerol accompanied the release of FFA during exercise. Glycerol-1-14C was oxidized by the exercising muscle. Glycerol dehydrogenase activity was demonstrated in human skeletal muscle.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
