Phenyl thio carbamide
WebQuestion: Ability to taste the chemical phenyl-thio-carbamide (PTC) is inherited with a dominant allele (A) causing ability to taste and the corresponding recessive (a) causing inability to taste. With rare exception, human eye color is inherited as if a dominant allele (B) causes brown eyes and the corresponding recessive (b) causes blue eyes. Phenylthiocarbamide (PTC), also known as phenylthiourea (PTU), is an organosulfur thiourea containing a phenyl ring. It has the unusual property that it either tastes very bitter or is virtually tasteless, depending on the genetic makeup of the taster. The ability to taste PTC is often treated as a dominant genetic trait, … See more The tested genetic taste phenomenon of PTC was discovered in 1931 when DuPont chemist Arthur Fox accidentally released a cloud of fine crystalline PTC. A nearby colleague complained about the bitter taste, while Fox, who … See more • TAS2R38 • PTC tasting • List of Mendelian traits in humans • Antidesma bunius • Propylthiouracil See more There is a large body of evidence linking the ability to taste thiourea compounds and dietary habits.
