Several different arachidonoyl amino acid conjugates, including N-<wbr></wbr>arachidonoyl dopamine and N-<wbr></wbr>arachidonoyl-<wbr></wbr>L-<wbr></wbr>serine, have been isolated and characterized from bovine brain. N-<wbr></wbr>Docosanoyl taurine is one of several novel taurine-<wbr></wbr>conjugated fatty acids discovered during mass spectrometry lipidomic analysis of brain and spinal cord from wild-<wbr></wbr>type and fatty acid amide hydrolase (FAAH) knockout mice. The levels of N-<wbr></wbr>docosanoyl taurine were elevated ~12 fold in FAAH-<wbr></wbr>/-<wbr></wbr> mice compared to wild-<wbr></wbr>type mice, indicating that FAAH utilizes N-<wbr></wbr>docosanoyl taurine as a substrate. However, in vitro experiments with purified FAAH indicate that related N-<wbr></wbr>fatty acyl taurines and ethanolamines of similar chain length are hydrolyzed 2,000-<wbr></wbr>50,000 times more slowly by FAAH compared to oleoyl ethanolamide. N-<wbr></wbr>acyl taurines bearing polyunsaturated acyl chains can activate members of the transient receptor potential (TRP) family of calcium channels, including TRPV1 and TRPV4.
