Arachidonic Acid-d11

Arachidonic acid-d11 contains 11 deuterium atoms at the 16, 16, 17, 17, 18, 18, 19, 19, 20, 20, and 20 positions. It is intended for use as an internal standard for the quantification of arachidonic acid (Cay-90010) by GC- or LC-mass spectrometry. 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. 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.Formal Name: 5Z,8Z,11Z,14Z-eicosatetraenoic-16,16,17,17,18,18,19,19,20,20,20-d11 acid.
