Arachidonic Acid (ARA), CAS number 506-32-1, is a polyunsaturated omega-6 fatty acid with the chemical formula C20H32O2 and a molecular weight of 304.47. It is a colorless to light yellow oily liquid with a slight characteristic odor. ARA has a melting point of approximately -49 °C and a boiling point of 169-171 °C at 0.15 mmHg. The density of ARA is about 0.922 g/mL at 25 °C, and its refractive index is n20/D 1.4872. It is practically insoluble in water but has good solubility in organic solvents like ethanol .
ARA is an essential fatty acid that plays a critical role in human health. It is a precursor to eicosanoids, which include prostaglandins, thromboxanes, and leukotrienes that are vital in various physiological processes such as inflammation, blood clotting, and immune function. Arachidonic Acid is found in high concentrations in the brain, muscles, and liver and is typically obtained through diet, with sources including meat, eggs, and certain fish
In the industrial sector, ARA is used as a nutritional supplement, especially in products designed to support cognitive function and joint health. It is also utilized in the pharmaceutical industry for the treatment of various conditions related to inflammation and immune response .
From a safety perspective, ARA is sensitive to light, temperature, and air, requiring proper storage conditions such as refrigeration at 2-8°C to maintain stability. It is also important to handle ARA with care due to its potential irritancy to skin, eyes, and the respiratory system
