What is arachidonic acid (AA)?

Arachidonic acid (AA) is an essential Omega-6 fatty acid that serves as a key component of cell membranes and a precursor to various signaling molecules. While the body can synthesize AA from linoleic acid, it is also obtained directly from dietary sources. AA is converted into eicosanoids, which are signaling molecules that play critical roles in inflammation and immunity.

  • People with diets either very high or very low in Omega-6 fatty acids.
  • Individuals concerned about cardiovascular health, given AA’s complex role in heart disease.

What is the role of role of AA in the body?

Arachidonic acid is integral to cell membrane structure and function, influencing membrane fluidity and the activity of various receptors and enzymes. It is a precursor to prostaglandins, thromboxanes, and leukotrienes, which are involved in the body’s inflammatory responses. While necessary for health, an imbalance in AA and its metabolites can contribute to chronic inflammation, playing a role in conditions like arthritis, cardiovascular diseases, and asthma.

What are the symptoms of AA deficiency?

  • Impaired growth and development in children.
  • Skin issues, such as dry or scaly skin.
  • Weakened immune response.
