A substance that tastes bitter to some persons but is tasteless to others. The ability to taste it is thought to be an autosomal dominant trait. P. contains the N–C=S group upon which the taste peculiarity apparently depends; goitrogenic or antithyroid substances ( e.g., thiourea and thiouracil), which also contain this group, possess the same property with respect to taste. SYN: phenylthiocarbamide.
