Arachidonic Acid (peroxide free)

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. Arachidonic acid oxidizes spontaneously on exposure to room air, yielding a complex mixture of fatty acid peroxides. Arachidonic acid (peroxide free) contains the antioxidant BHT (Cay-89910). BHT-free arachidonic acid (Cay-90010, Cay-10006607) is also available.Formal Name: 5Z,8Z,11Z,14Z-eicosatetraenoic acid. CAS Number: 506-32-1. Synonyms: AA (peroxide free), FA 20:4.
