PTC (phenylthiocarbamide)The ability to taste PTC (or not) is conveyed by a single gene that codes for a taste receptor on the tongue. The PTC gene, TAS2R38, was discovered in 2003. Studies suggest a correlation between the ability to taste PTC and preferences for certain types of food (“PTC: Genes,” n.d.)
