OR51E1 15.3512 60.5968 52.696 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).
