molecular function
    GO:0035275    dibutyl phthalate binding    Interacting selectively and non-covalently with dibutyl phthalate, C(16)H(22)O(4).
    GO:0035274    diphenyl phthalate binding    Interacting selectively and non-covalently with diphenyl phthalate, C(20)H(14)O(4).
    GO:0005549    odorant binding    Interacting selectively and non-covalently with an odorant, any substance capable of stimulating the sense of smell.
biological process
    GO:0042048    olfactory behavior    The behavior of an organism in response to an odor.
    GO:0007608    sensory perception of smell    The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors. This is a neurological process.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
