Chemical Information
FooDB Name12-KETE
Description12-keto-eicosatetraenoic acid is a biologically active eicosanoid in the nervous system of Aplysia.It is a metabolite of 12-HPETE formed by Aplysia nervous tissue. 12-KETE was identified in incubations of the tissue with arachidonic acid using HPLC, UV spectrometry, and gas-chromatography/mass spectrometry. [3H]12-KETE is formed from endogenous lipid stores in nervous tissue, labeled with [3H]arachidonic acid upon stimulation by application of histamine. In L14 and L10 cells, identified neurons in the abdominal ganglion, applications of 12-KETE elicit changes in membrane potential similar to those evoked by histamine.[PMID:2774398] [HMDB]
