a long-chain of polyunsaturated fatty acid that is a component of most cell membranes. When liberated from the membrane by the enzymatic activity of phospholipase A2, this acid is transformed into a s [..]

This is one of the essential fatty acids in the body. This means that it can not be produced by the body, but needs to be absorbed from the diet. Arachidonic acid helps promote clumping and aggregatio [..]

An unsaturated, essential fatty acid. It is found in Animal and Human fat as well as in the liver, Brain, and glandular organs, and is a constituent of Animal Phosphatides. It is formed by the synthes [..]

Arachidonic acid (AA) is an essential omega-6 fatty acid (see essential fatty acids).

Eicosatetraenoic acid, a precursor for the synthesis of signaling molecules, such as prostaglandins and thromboxanes. Arachidonic acid is released from cell membrane phospholipids, including phosphatidyl inositol, by phospholipases.

An unsaturated fatty acid

<biochemistry> An essential dietary component for mammals. The free acid is the precursor for biosynthesis of prostaglandins, thromboxanes, hydroxyeicosatetraenoic acid derivatives including leucotrienes and is thus of great biological significance. Within cells the acid is found in the esterified form as a major acyl component of membrane ph [..]

An omega-6 fatty acid. Arachidonic acid is the compound from which inflammatory mediators such as leukotrienes, thromboxanes, and prostaglandins are produced.

A fatty acid that becomes essential when a linoleic-acid deficiency exists.
