phenylthiourea


Also found in: Dictionary, Encyclopedia, Wikipedia.

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

xylostella larvae were homogenized in a Waring blender in 250 ml of a high salt buffer (0.5 M NaCl, 50 mM Tris, pH 7.5) containing 1 mM phenylmethylsulfonyl fluoride (PMSF; a serine protease inhibitor) and saturated with phenylthiourea (a tyrosinase inhibitor).
The hemolymph was drawn from the coxal joint into an Eppendorff Pipetman containing a few milligrams of phenoloxidase inhibitor (phenylthiourea) to prevent tanning or darkening and then diluted 5 times with 0.7% saline solution.
