Abstract

The previous finding that only one half of a disaccharide molecule binds to the taste receptor site is fully substantiated but the linkage and the sugar residues of the disaccharide are important. The study is extended to the field of bitterness and it is observed that binding on to the bitter receptor is analogous to that on to the sweet receptor. With reducing disaccharides, it is the non‐reducing glycosyl unit that binds to the taste bud protein. Therefore, oligosaccharides constitute ideal models for this study despite their free anomeric centres.

The preferable structural feature for sweetness is a lipophilic moiety, e.g., a fiveor six-membered ring with a polar substituent containing an A-H/B system outside the ring. In ketoses, this unit is probably the 1,2-glycol. If a third feature (the lipophilic, 7, site) is required for the attainment

Transcriptional regulation is coupled with numerous intracellular signaling processes often mediated by second messengers. Now, growing evidence points to the importance of Ca(2+), one of the most versatile second messengers, in activating or inhibiting gene transcription through actions frequently
