Description

General description

A cis-polyunsaturated fatty acid found in the plasma membrane. Major component of membrane phospholipids. Following its release by cellular phospholipases, it is enzymatically converted to a variety of inflammatory and vasoactive metabolites, such as prostaglandins (via the cyclooxygenase pathway), leukotrienes (via the lipoxygenase pathway), and epoxides (via the cytochrome P450 pathway). Binds to G-protein α-subunits in a covalent, posttranslational manner. Inhibits Ras-GAP. Stimulates the synthesis of nitric oxide by platelets.

Precursor for prostaglandins, prostacyclin, and thromboxane. Binds to G-protein α-subunits in a covalent, post-translational manner. Inhibits Ras-GAP. Stimulates the synthesis of nitric oxide by platelets. Modulates nitric oxide production by prostaglandin synthesis via the cyclooxygenase pathway.
