Receptor Dock Score Affinity A100 Correlated Perceptual Qualities
OR51E2 31.2231 35.214 48.8866 vinegar, sour, sharp, radish
OR51E1 22.642 25.5363 51.5675 cheesy, sweaty, sour, acidic

Dock Score: This is a measure of whether the algorithm thinks the odorant is an agonist of the receptor.
Affinity: The binding affinity, in kJ/mol, of the ligand docked in the active or inactive model, whichever is greater.
A100: A measure of the degree of activation of the receptor. See Ibrahim et al (2019).
