N-Acyl taurines, such as N-lignoceroyl taurine, alongside various arachidonoyl amino acid conjugates like N-arachidonoyl dopamine and N-arachidonoyl-L-serine, have been identified in bovine brain and through mass spectrometry lipidomic studies in the brain and spinal cord of both wild-type and FAAH knockout mice. Notably, N-lignoceroyl taurine levels were found to be 23-26 times higher in FAAH knockout mice than in wild types, suggesting its degradation by FAAH, despite in vitro evidence showing FAAH hydrolyzes N-lignoceroyl taurine significantly slower than oleoyl ethanolamide. Additionally, N-acyl taurines with polyunsaturated acyl chains are known to activate TRPV1 and TRPV4 channels within the transient receptor potential (TRP) family of calcium channels.
