Tasting bitterness in brassicas
rs1726866 · chr7:141,672,705 · A/G · evidence: established
TAS2R38 detects a specific bitter compound found in broccoli, sprouts and kale. Two common versions of the receptor differ at three positions, and one of them barely works.
| If you carry | What it means |
|---|---|
