Notes: Arachidonic acid-d5 is intended for use as an internal standard for the quantification of arachidonic acid (Item Nos. 90010 / 90010.1 / 10006607) by GC- or LC-MS. Arachidonic acid is an essential fatty acid and a precursor for all prostaglandins, thromboxanes, and leukotrienes. Virtually all cellular arachidonic acid is esterified in membrane phospholipids where its presence is tightly regulated through multiple interconnected pathways.{3656} Free arachidonic acid is a transient, critical substrate for the biosynthesis of eicosanoid second messengers. Receptor-stimulated release, metabolism, and re-uptake of free arachidonate are all important aspects of cell signaling and inflammation.{314}
