2009). Rather, there can be an anatomical demarcation in enzymes that regulate this process in which MAGL plays this role not only in the brain, but also in the liver and lung, whereas cytosolic phospholipase A2 (cPLA2) is the dominant AA-releasing enzyme in gut, spleen and macrophages (Bonventre et al.

2004). Although ABHD12 and ABHD6 may possess assignments in 2-AG hydrolysis using configurations, both hereditary and pharmacological inactivation of MAGL result in dramatic elevations in both mass amounts and depolarization-induced interstitial degrees of 2-AG in the mind, confirming that MAGL is definitely the principal enzyme involved with degrading 2-AG (Longer et al.

Precursor3
The lipid precursor phosphatidylethanolamine (PTLM), through the action of N -acyltransferase (NAT) and of arachidonic acid (ARa), leads to the formation of N -arachidonoyl-phosphatidylethonolamine (NAPE), which, through the action of NAPE-phospholipase D (NAPE-PLD), forms N -Arachidonoylethanolamine (anandamide-AEA) and phosphatidic acid (PHa).
