This week a TPL Kids website visitor is wondering why sugar is sweet.
An article in Nature: International Journal of Science, highlighted research conducted at the Roma Tre University in Rome. It found that fructose, glucose and mannose each formed hydrogen bonds of different lengths. Sweeter-tasting sugars formed tighter, stronger bonds. The strength of the molecules’ hydrogen bonds may be the primary factor in determining a sugar’s level of sweetness.
That’s a pretty sweet answer, no?
