Identified herein are different forms of bitter receptor genes that occur in different humans. These alleles are generated by numerous coding single nucleotide polymorphisms (cSNP's) that occur within the members of the T2R gene family. Some SNP's cause amino acid substitutions, while others introduce chain termination codons, rendering the allele non-functional. Differences in these genes are believed to have a large effect on those individuals' sense of bitter taste, such that these individuals perceive the taste of bitter substances differently than the rest of the population. The ability to assay this allelic information is useful in the development of flavorings and flavor enhancers, as it can be used to define large groups and populations who perceive bitter tastes differently. This in turn allows the taste preferences of these groups to be addressed at the molecular level for the first time.

Appetite control compositions comprise Gymnema sylvestre and an expectorant. In some embodiments, the appetite control compositions contain from about 3 mg to about 50 mg of gymnemic acid (an extract of Gymnema sylvestre), from about 10 mg to about 80 mg of glycyrrhizin (an extract of Glycyrrhiza glabra), high impact flavor, and a sweetening agent in a non-traditional dosage form. A non-traditional dosage form provides for the topical application of medicaments to the tissues of the mouth and tongue, more specifically, to the sweetness taste receptors of the tongue. By delivering gymnemic acid to the sweetness receptors of the tongue, the sensation of sweetness is blocked, thereby providing appetite control.

The use of sensory G protein-coupled receptors that recognize chemical sensants, parti-cularly those involving olfactory and taste receptors; polypeptide fragments and mutants thereof; classes of such receptors; polynucleotides encoding such receptors, fragments and mutants thereof, and representatives of receptor classes; genetic vectors including such polynucleotides; and cells and non-human organisms engineered to express such receptor complexes, fragments and mutants of an olfactory or taste receptor, and representatives of receptor classes to simulate sensory perception of odorants and tastants is described. The use of such products as a biosensor or a component thereof to detect, identify, measure, or otherwise process the event of binding between the receptor and its cognate ligand (i.e., chemical sensant) is also described. The invention has application, for example, in the design and formulation of odorant and tastant compositions.

This invention provides isolated nucleic acid and amino acid sequences of gastrointestinal endocrine cell specific G-protein coupled receptors, methods of detecting such receptors, and methods of screening for ligands of such receptors. Furthermore, this invention demonstrates that SrC-1 enteroendocrine cells express multiple bitter taste receptors as well as a-subunits of G proteins that mediate taste signal transduction and respond to bitter taste compounds initiating changes in intracellular calcium concentration. Given that at present there are no cultured cell model system to determine the functional effects of taste receptor-mediated signaling, our findings identify STC-1 cells as a cell model for studying taste-mediated signal transduction.
