Pronunciation: fen'il-thi'o-yu-re'a

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

See: taste deficiency

Synonym(s): phenylthiocarbamide
