Before revision: Human olfactory receptor , OR1D2, binds to Bourgeonal , a chemical constituent of the mythical flower, Lily of the valley or Our Lady's tears (1) . OR1D2, OR1D4 and OR1D5 are three full length olfactory receptors present in an olfactory locus in human genome.
After revision: Ligands for only two human olfactory receptors are known. One of them , OR1D2, binds to Bourgeonal , a chemical constituent of the mythical flower, Lily of the valley or Our Lady's tears (1) . OR1D2, OR1D4 and OR1D5 are three full length olfactory receptors present in an olfactory locus in human genome.
