arachidonic acid usage and synthesis
chemical properties liquid
usage an unsaturated omega-6 fatty acid constituent of the phospholipids of cell membranes
usage arachidonic acid is an essential fatty acid and a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes. arachidonic acid occurs in liver, brain, glandular organs, and depot fats of animals, in small amounts in human depot fats, and arachidonic acid is also a constituent of animal phosphatides.
biological activity endogenous free fatty acid released from phospholipids by phospholipase a 2 . important cellular signaling mediator and precursor of eicosanoids. metabolized by lipoxygenases, cyclooxygenases and cytochrome p450 monooxygenases.
