SMILES:
O1C(CC)=C(O)C(=O)[C@@H](C)1
Aroma Description:
sweet, cotton_candy, burnt_sugar, sugar, caramellic, bready1
caramellic2
Notes:
The keto-enol tautomers and their enantiomers exist together in an equilibrium. The isomer shown is the only one with a strong sweet-roasty olfactive impact.

Dock Score is a measure of how strongly the algorithm thinks the odorant is likely to be an agonist of the receptor.
Receptors in italics are "orphans", i.e. receptors whose agonists have not been identified experimentally.
