Deeper understanding of signaling mechanisms underlying bitterness perception in people is essential for designing novel and effective bitter blockers, which could enhance nutrition and compliance with orally administered bitter-tasting drugs. Here we show that variability in a human odorant-binding protein gene, OBPIIa, associates with individual differences in bitterness perception of fat (oleic acid) and of a prototypical bitter stimulus, 6-n-propylthiouracil (PROP), suggesting a novel olfactory role in the modulation of bitterness sensitivity.
