The Shallenberger AH,B theory of sweetness' suggests that the fundamental unit of sweetness of a compound is an AH,B system, where A and B are each electronegative atoms in suitable geometric proximity. This unit can hydrogen bond with a complementary AH,B system in the receptor protein of the taste
cY,cu'-Trehalose, when dried to a moisture content of ca. 5% from aqueous sodium phosphate buffer (with an initial pH I 5.5), produces, after warming, a mixture containing the four isomeric monophosphate esters which can be isolated by anion-exchange chromatography. Their structures were deduced fro
