Tetradecanedioic acid
Tetradecanedioic acid, also known as 1,14-tetradecanedioate or NSC 9504, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Tetradecanedioic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Tetradecanedioic acid is a C14 dicarboxylic acid. [HMDB] Tetradecanedioic acid is an endogenous metabolite and belongs to the class of organic compounds known as long-chain fatty acids. Tetradecanedioic acid can act as a candidate biomarker for organic anion-transporting polypeptide mediated agent-agent interactions [1].

3-hydroxypentadecanoic acid
3-Hydroxypentadecanoic acid is a long-chain hydroxy fatty acid. In humans fatty acids are predominantly formed in the liver and adipose tissue, and mammary glands during lactation.
Decanoylcholine
Decanoylcholine is a fatty acid-choline as the ester product of Decanoic acid and cholinel. 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 shortchain 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. Decanoylcholine is a fatty acid-choline as the ester product of Decanoic acid and cholinel.
