Arachidonic Acid (sodium salt)

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)
