Study Notes
Eicosanoids and Arachidonic Acid
- Arachidonic acid is the most abundant precursor of eicosanoids.
- Cytosolic phospholipase A2 is the most dominant type of lipase in the acute release of arachidonic acid.
- Phospholipase A2 is involved in sustained or intense stimulation of arachidonic acid production.
Arachidonic Acid Oxygenation
- One route that is NOT involved in arachidonic acid oxygenation is direct degradation by oxygenases.
Eicosanoid Synthesis
- The type of eicosanoids synthesized is determined by factors such as the type of cell, substrate availability, and the enzyme pathway.
- The type of cell is a factor that determines the type of eicosanoids synthesized.
General Facts
- Arachidonic acid is a 20-carbon fatty acid.
- Eicosanoids are not unique to animals and can be found in other organisms.
- Phospholipase C and diglyceride lipase can release arachidonic acid from membrane phospholipids.
- Arachidonic acid can be oxygenated by five separate routes.
