In 1999, Mark Hoon and a team of researchers discovered a gene family that codes for taste receptors, specifically for the "bitter" flavor which they called the TAS2R gene family. The locus of the gene (or genes) that control for PTC tasting is hypothesized to be a part of this TAS2R gene family. In 2003, Dennis Drayna and his colleagues at the National Institutes of Health (NIH), as well as a team of researchers led by Un-kyung Kim, discovered that a variation at the TAS2R38 gen… WebMar 29, 2024 · Something bitter might make us learn to avoid this food item in the future. One type of bitter receptor senses the presence of a chemical called phenylthiocarbamide ( PTC ). This chemical chemically resembles toxic compounds found in plants but is non-toxic. The ability to taste PTC comes from a gene called TAS2R38.
