Arachidonic Acid (sodium salt)

Polyunsaturated fatty acids (PUFAs) are essential nutrients that show distinct deficiency syndromes when not present in adequate amounts in the diet.{5525,8460} 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 signalling and inflammation.{314}
