According to the different molecular structures, sweet molecules can be divided into sugars(sugar, sugar derivatives、sugar alcohols、glycosides), amino acids(dipeptides、proteins), sulfonamides and so on. This article will explain sweet molecules and their sweetness from the molecular structure level.
