Arachidonic Acid Metabolism Service

Online Inquiry


Arachidonic acid is a 20-carbon polyunsaturated fatty acid and the central eicosanoid precursor in mammalian cells.  It is structurally related to the saturated arachidic acid found in cupuaçu butter. Since arachidonic acid cannot be synthesized de novo from animal cells, most of arachidonic acid in the animal is derived from linoleic acid, which can be obtained only from dietary sources. After biosynthesis of arachidonic acid from its precursor, it is esterified into the phospholipids of the outer cell membranes.  Therefore, the first step in the arachidonic acid metabolism is cleavage and release of arachidonic acid from the phospholipid-bound form via phospholipase A2 (PLA2), phospholipase C and phospholipase D (Figure 1). The majority of arachidonic acid metabolites can act both as pro- and anti-inflammatory mediators, modulating gene expression, cytokine signalling and other immune regulatory factors. So the aberrant arachidonic acid metabolism is closely related to a variety of human diseases like gastrointestinal ulceration and cancer. In Creative Proteomics, we provide reliable, rapid and cost-effective arachidonic acid metabolism related service to speed up your research aims ranging from diseases diagnosis to gaining new insights in disease mechanism or treatment.
