Arachidonic acid is a lipid of Fatty Acyls (FA) class. Arachidonic acid is associated with abnormalities such as Atherosclerosis, Ischemia, Hypertensive disease, Hypertension induced by pregnancy and Vascular ring of aorta. The involved functions are known as Platelet aggregation, Anabolism, Ion Transport, Signal Transduction Pathways and Signal. Arachidonic acid often locates in Extracellular, Body tissue, Protoplasm, Tissue membrane and soluble. The associated genes with Arachidonic acid are CYP2J2 gene, CYP2E1 gene, Recombinant Proteins, POR gene and P4HTM gene. The related lipids are Fatty Acids, Glycerophospholipids, Steroids, octadecadienoic acid and 9-hydroxy-10,12-octadecadienoic acid. The related experimental models are Mouse Model and Knock-out.
