Arachidic acid is a lipid of Fatty Acyls (FA) class. Arachidic acid is associated with abnormalities such as nervous system disorder, Liver diseases, Obesity, Diabetes Mellitus, Non-Insulin-Dependent and Cardiovascular Diseases. The involved functions are known as Process, Regulation, Saturated, Oxidation and enzyme activity. Arachidic acid often locates in Mitochondria, Brown Fat, Microsomes, Membrane and Muscle. The associated genes with Arachidic acid are ELOVL3 gene, P4HTM gene, CFLAR gene, Homologous Gene and Polypeptides. The related lipids are Fatty Acids, Glycerophospholipids, Palmitates, Stearic acid and hexadecenoic acid.
