Application

Arachidic acid has been used as a fatty acid standard to optimize a sensitive high-performauce liquid chromatography (HPLC) method to analyse fatty acid (FA) for the quantification of polyunsaturated FAs (PUFAs) in cell lipid extracts.

Biochem/physiol Actions

Arachidic acid is a saturated fatty acid with a 20 carbon chain. Arachidic acid occurs naturally in fish and vegetable oils. Diets rich in saturated fats like arachidic acid are associated with increased levels of serum low density lipoproteins.
