A small amount of fructose per day sustained a large weight loss for more than one year, with no sign of regain. Open symbols indicate periods without any treatment (no fructose or anything else). Quantification of unmetabolised fructose and glucose, containing also pentoses derived from the pentose phosphate pathway, was made in the void volume of the column. The glucose/fructose concentration ratio was generally between 1 and 1.6 in all organs. According to the explanation described below, the crucial feature of the fructose water was that it supplied calories with no flavor except sweetness. The metabolism and conversion of fructose and glucose are not equivalent even though carbon dioxide production is similar and increasing from morula to blastocyst. Species consumed contained a relatively greater amount of monosaccharides: 45% + 17.5% of total sugars was glucose, 47% + 19.3% fructose, and only 7.7% + 12.4% was sucrose. Similarly, at the intraspecific level, food-fruits had significantly more fructose and glucose than non-food fruits, but no difference was found for sucrose. The percentage of the original labelling remaining in the embryos at the end of the chase is similar for glucose and fructose (around 14%). Neither glucose nor fructose were detected in seeds from any of the 28 treatment combinations (data not presented). Further studies are needed to determine whether the positive effect of fructose supplementation in medium correlates with in vivo embryo development or not. The sugars in cacao endosperm were mainly reducing sugars: glucose and fructose. That sucrose and fructose had similar effects implies that the low glycemic index of fructose was irrelevant. Free galactose does not accumulate during germination, but other reducing sugars, including fructose, glucose and maltose do accumulate. These examples are from corpora and from sources on the web.
