n. Abbr. PTC
A crystalline compound, C7H8N2S, that tastes intensely bitter to people with a specific dominant gene and is used to test for the presence of the gene. Also called phenylthiourea.

Compared with the human TAS2R38 receptor, the cat receptor was 10 times less sensitive to a key bitter compound called phenylthiocarbamide (PTC).
Supertasters are defined by whether they can detect the presence of two bitter-tasting compounds, phenylthiocarbamide (PTC) and propylthiouracil (PROP), and geneticists have shown that this ability depends to a large extent on certain variations of a gene known as TAS2R38.
