Figure 1

1H-NMR spectrum of (a) NADPH, (b) (4R)-[Ad-14C,4-2H]-NADPH. The peaks shown represent the hydrogens at C4 of the product with the pro-R hydrogen at 2.935 PPM and the pro-S hydrogen at 2.822 PPM. In spectrum b, integration of the noise at and around 2.935 PPM indicated that up to 0.3 % 1H contamination would have been detectable if present. Since none is detected the H-contamination is less than 0.3 %.
