phenylthiourea

phen·yl·thi·o·u·re·a

(fen'il-thī'ō-yū-rē'ă),

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 (for example, thiourea and thiouracil), which also contain this group, possess the same property with respect to taste. See: taste deficiency.

Synonym(s): phenylthiocarbamide
