Ptc Bitter Taste Gene. Depending on what genes a person has PTC can taste vastly different. Genetic variation in sensitivity towards PTC and PROP may affect food preferences and susceptibility to certain diseases. Two copies of form 3. This altered shape means that the persons receptors will not respond to PTC and the person will not think the PTC tastes bitter.
The TAS2R38 gene contains genetic information for a taste receptor that can detect chemicals like phenylthiocarbamide or PTC. The shape of the receptor protein determines how strongly it can bind to PTC. Since all people have two copies of every gene different combinations of the bitter taste gene two copies of form 1. Some people find the substances phenylthiocarbamide PTC and 6-n-propylthiouracil PROP to have an extremely bitter taste while others dont taste them at all. Two copies of form 3. This phenotype is of genetic epidemiologic and evolutionary interest because the ability to taste PTC is correlated with the ability to taste other bitter substances many of which are toxic.
Resources target primary and secondary school levels.
The ability to test phenylthiocarbamide PTC is a classic phenotype that has long been known to vary in human populations. The ability to taste phenylthiocarbamide PTC is a classic phenotype that has long been known to vary in human populations. To some PTC tastes extremely bitter. The ability to taste PTC comes from the gene TAS2R38 which encodes one of the chemical receptors in our mouth that binds to PTC. The ability to test phenylthiocarbamide PTC is a classic phenotype that has long been known to vary in human populations. Learn how our taste buds work and why some of us are sensitive to bitter tastes.
