“ Xylitol (5 mm) served as a strong reductant for cytosolic NAD systems as shown by increased ratios of lactate to pyruvate, α-glycerophosphate to dihydroxyacetone-P, and triose phosphates to 3-P-glycerate.”
“ Xylitol also caused an increased reduction of bound NAD as determined analytically and by increased pyridine nucleotide fluorescence measured by surface fluorometry.”
