The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. Combining with acetylcholine to initiate a change in cell activity. Interacting selectively and non-covalently with any organic compound that is weakly basic in character and contains an amino or a substituted amino group. Interacting selectively and non-covalently with acetylcholine, an acetic acid ester of the organic base choline that functions as a neurotransmitter, released at the synapses of parasympathetic nerves and at neuromuscular junctions. Interacting selectively and non-covalently with a neurotransmitter, any chemical substance that is capable of transmitting (or inhibiting the transmission of) a nerve impulse from a neuron to another cell.
