Arachidonic Acid-biotin

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 signalling and inflammation. Arachidonic acid-biotin was designed to allow arachidonic acid to be detected in complexes with protein binding partners such as fatty acid binding proteins (FABPs). It is thus a tool to be used in the general elucidation of the signaling and transport of free arachidonic acid.
