Chemistry. Acetylcholine is a choline molecule that has been acetylated at the oxygen atom. Because of the presence of a highly polar, charged ammonium group, acetylcholine does not penetrate lipid membranes. Is acetylcholine water soluble? Solubility: Soluble in water (100mg/ml) or alcohol; insoluble in ether.
