Question 1 1 / 1 pts For the next 9 questions, we will review the PTC tasting study with different data. And some people don’t. The objective of this study is to review the association of TAS2R38 polymorphisms and taste phenotypes to bitter compounds (phenylthiocarbamide [PTC]/propylthiouracil [PROP]), and its association among persons who drink alcohol and individuals with smoking behavior. PTC-tasting ability is not particularly useful, it would seem, since PTC does not occur in food, but some substances related to PTC do occur in food items.
