    Product Description

    1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA is a phospholipid containing arachidonic acid at the sn-1 position. It has been found in rat brain as 37% of the arachidonic acid-containing lysophosphatidic acid (LPA) species and is a precursor to 1-arachidonoyl glycerol (1-AG; Item No. 62150).1 1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA binds to the LPA2/EDG4 receptor with an EC50 value of approximately 10 nM.2 It prevents TNF-α and IL-6 secretion in wild-type but not Lpa2-/- dendritic cells stimulated by LPS.3 It also decreases differentiation of HT-29 human colon carcinoma cells to goblet cells in the presence of sodium butyrate.4
