WebJan 1, 2001 · The ability to taste some bitter compounds is genetically determined ( Snyder, 1931 ). Two compounds, phenylthiocarbamide (PTC) and 6- n -propylthiouracil (PROP), taste bitter to some people and are tasteless to others ( Blakeslee and Fox, 1932; Fox, 1932; Fischer, 1964 ). The tested genetic taste phenomenon of PTC was discovered in 1931 when DuPont chemist Arthur Fox accidentally released a cloud of fine crystalline PTC. A nearby colleague complained about the bitter taste, while Fox, who was closer and should have received a strong dose, tasted nothing.
