Ptc paper where to buy

This product is all you need for a demonstration of genetics and heredity. The strip can taste anywhere from bland to incredibly bitter for individuals depending on their genotype and phenotype. PTC Paper has been used widely since its discovery to detect genetic variation in tasting abilities. Phenylthiocarbamide PTC is a chemical which causes a bitter flavor to some people. Research suggest it is related to an enzyme which is produced by cells on the tongue.

Though not essential for survival, this condition might explain why some people are more sensitive to bitter tastes than others. Instructions: 1. Remove a PTC taste test paper from the vial. Stick out your tongue, and place the strip on your tongue. There are three basic results: bland, bitter, or vile. They won't let you down, no matter what they're up against.
