Differences in acetate recovery factor between groups may interfere with tracer estimates of fat oxidation (letter to the editor)

L.B. Borghouts (Lector); E.E. Blaak; P. Schrauwen; A.J.M. Wagenmakers

This letter to the editor argues that the assumption of a single value for the acetate recovery factor in carbon-13 stable isotope research for different individuals, can lead to significant errors in the outcomes of substrate utilization measurements.

Determinants of the acetate recovery factor: implications for estimation of 13C substrate oxidation.

P. Schrauwen; E.E. Blaak; A.J.M. Wagenmakers; L.B. Borghouts (Lector); Dorien P.C. van Aggel-Leijssen

The data of this study indicate that the acetate recovery factor, used in stable isotope research, needs to be deteremined in every subject, under similar conditions as used for the tracer-derived determination of substrate oxidation.

Synthesis of α- and β-D-glucopyranuronate 1-phosphate and α-D-glucopyranuronate 1-fluoride: intermediates in the synthesis of D-glucuronic acid from starch

Heeres, André (Biobased Ingredients And Materials); Van Doren, Henk A.; Gotlieb, Kees F.; Bleeker, Ido Pieter

The title uronates were prepared by 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) catalysed sodium hypochlorite oxidation of α- and β-D-glucopyranosylphosphate (α-/β-Glc-1-P) and α-D-glucopyranosyl fluoride (α-Glc-1-F). Quantitative recovery of the TEMPO catalyst was achieved by azeotropic distillation …

Reduced oxidation rates of ingested glucose during prolonged exercise with low endogenous CHO availability

A.E. Jeukendrup; L.B. Borghouts (Lector); W.H.M. Saris; A.J.M. Wagenmakers

This paper descibes a study that shows that glycogen-lowering exercise, performed the evening before an exercise bout in combination with glycogen restriction leads to a reduction of the oxidation rate of ingested glucose during moderate-intensity exercise
