9-Hexadecenoylcholine
9-Hexadecenoylcholine, also known as palmitoloelycholine, is a fatty acid-choline and is the ester product of 9-hexadecenoic acid and choline. The pharmacological effects of a series of fatty acid-choline esters have been studied on the isolated rabbit heart, the isolated guinea-pig ileum, and the rat stomach. The effect changed with increasing chain length, and three different types of response were observed. The short-chain compounds produced depression of the isolated rabbit heart and spasm of the isolated guinea-pig ileum. Only one, butyrylcholine, had an erratic stimulating effect on hydrochloric acid secretion by the partially vagotomized rat stomach. Medium-chain compounds had a stimulating effect on the isolated rabbit heart, a mixed spasmogenic and relaxant effect on the isolated guinea-pig ileum, and no effect on the rat stomach. Long-chain compounds blocked the effect of acetylcholine on the isolated rabbit heart and the isolated guinea-pig ileum; they also depressed spontaneous hydrochloric acid secretion by the rat stomach. 9-Hexadecenoylcholine is a fatty acid-choline as the ester product of 9-Hexadecenoic acid and cholinel.
