Also known as: Arachidonic Acid (AA), Arachidonic Acid/EPA Ratio, DHA, EPA, Omega-3 Index, Omega-6/omega-3 Ratio, Omega3 and 6 Fatty Acids Plasma, Phospholipid Omega-3 Fatty Acid, Phospholipid Omega-6 Fatty Acid, Polyunsaturated Fatty Acids (PUFAs)

ARACHIDONIC ACID

Arachidonic acid is a polyunsaturated fatty acid present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine, and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain, muscles, and liver. In addition to being involved in cellular signaling as a lipid second messenger involved in the regulation of signaling enzymes, such as PLC-γ, PLC-δ, and PKC-α, -β, and -γ isoforms, arachidonic acid is a key inflammatory intermediate and can also act as a vasodilator

ARACHIDONIC ACID/EPA

Arachidonic acid is a polyunsaturated fatty acid present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine, and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain, muscles, and liver. In addition to being involved in cellular signaling as a lipid second messenger involved in the regulation of signaling enzymes, such as PLC-γ, PLC-δ, and PKC-α, -β, and -γ isoforms, arachidonic acid is a key inflammatory intermediate and can also act as a vasodilator

DHA

The omega-3 fatty acids EPA and DHA are found in seafood, such as fatty fish (e.g., salmon, tuna, and trout) and shellfish (e.g., crab, mussels, and oysters).

EPA

The omega-3 fatty acids EPA and DHA are found in seafood, such as fatty fish (e.g., salmon, tuna, and trout) and shellfish (e.g., crab, mussels, and oysters).

OMEGA 3 (EPA+DHA) INDEX

Omega-3 (n-3 polyunsaturated) fatty acids are essential fats that your body needs to function properly but does not make. Humans must eat them through food, which means getting EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) from seafood, such as salmon, tuna, sardines, mackerel or shellfish, and ALA (alpha-linolenic acid) from sources such as walnuts, flaxseed, and canola and soybean oils. Omega-3 fatty acids, particularly EPA and DHA, have been shown to benefit the heart of healthy people, and those at high risk for — or who already have — cardiovascular disease.

OMEGA 6/OMEGA 3 RATIO

Omega-6 (n-6 polyunsaturated) fatty acids are the other group of essential fats that your body needs to function properly but does not make. Hence, they need to be consumed in the diet. Food sources of omega-6 fatty acids include some vegetable oils (soybean, safflower, sunflower or corn oils), nuts and seeds. Increased consumption of omega-6 fatty acids in place of saturated fats and trans fats is associated with a decreased risk of coronary heart disease.
