Arachidonic acid is metabolized by cytochrome P450 (CYP450) 4A ω-hydroxylase to 20-HETE, which acts as a vasoconstrictor in the kidney and brain.1 During mass spectrometry lipidomics analysis of rat brain, a series of fatty acyl amides of taurine was discovered, of which arachidonoyl taurine is a prominent member.2 20-hydroxy N-Arachidonoyl taurine is a potential CYP450 metabolite of N-arachidonoyl taurine and may activate members of the transient receptor potential (TRP) family of calcium channels.3WARNING This product is not for human or veterinary use.
