Adrenic acid

Adrenic Acid (cis-7,10,13,16-Docosatetraenoic acid) is a naturally polyunsaturated fatty acid in the adrenal gland, brain, kidney, and vasculature. Adrenic Acid can regulate the vascular tone in arteries of the adrenal cortex. Adrenic Acid also is an inflammation enhancer in non-alcoholic fatty liver disease^[1][2]. In Vitro: Adrenic acid is produced via the elongation of arachidonic acid by ELOVL2 and 5. Interestingly, the hepatic level of free Adrenic Acid (22:4n6) is markedly higher in the CDAHFD-fed db/db mice than in the SD-fed db/db mice. In plasma, the difference in the adrenic acid level reaches statistical significance (p<0.001). It is also found that the concentrations of phospholipid species containing Adrenic Acid, such as PC or PE (40:4) (containing side chain 18:0/22:4), and LPC 22:4 (sn-1/sn-2), are also significantly increased. (sn-1/sn-2). The hepatic and plasma levels of Adrenic Acid, which is an omega 6 polyunsaturated fatty acid (PUFA), exhibit greater differences between the CDAHFD-fed db/db mice and the SD-fed db/db mice (8.6-fold higher vs. 1.6-fold higher in liver tissue, 5.3-fold higher vs. 2.2-fold higher in plasma) than those of well-known proinflammatory PUFA, such as Arachidonic Acid^[1].
