Receptor mechanism producing a sweet taste from plant aroma compounds.

ABSTRACT: Fruits and vegetables contain highly volatile hydrophobic small molecules responsible for their aroma, taste, and pungency. Empirically, we understand that these compounds can evoke a sweet taste; however, their specific interactions with sweet taste receptors are unclear. To address this issue, HEK293 cells expressing human and mouse sweet taste receptors TAS1R2/TAS1R3 were used to identify trans-2-hexenal (a novel sweetener) in human and cinnamyl alcohol (a sweetness inhibitor) in mice. The effects of these compounds on TAS1R2/TAS1R3 in humans and mice were evaluated alongside known hydrophobic sweet compounds, and the results showed that they elicited responses in human TAS1R2/TAS1R3 but not in mice. Conversely, some compounds inhibited the sweetness of sucralose both in vitro and in vi
