Arachidonic Acid sulfonate (sodium salt)

Arachidonic acid (Item No. 90010) 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} Arachidonic acid sulfonate has a sulfonate group linked to the a-carbon of arachidonic acid, which creates a dissymmetric molecule with potentially improved lipophilicity.
