Prostaglandin H2 is a type of Prostaglandin
Prostaglandin
A prostaglandin is any member of a group of lipid compounds that are derived enzymatically from fatty acids and have important functions in the animal body. Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring....

 which is derived from arachidonic acid
Arachidonic acid
Arachidonic acid is a polyunsaturated omega-6 fatty acid 20:4.It is the counterpart to the saturated arachidic acid found in peanut oil, Arachidonic acid (AA, sometimes ARA) is a polyunsaturated omega-6 fatty acid 20:4(ω-6).It is the counterpart to the saturated arachidic acid found in peanut oil,...

 and is a precursor for many other biologically significant molecules.

It is acted upon by:
  • prostacyclin synthase
    Prostacyclin synthase
    Prostaglandin-I synthase also known as prostaglandin I2 synthase or CYP8A1 is an enzyme involved in prostanoid biosynthesis that in humans is encoded by the PTGIS gene. This enzyme belongs to the family of cytochrome P450 isomerases.- Function :This gene encodes a member of the cytochrome P450...

     to create prostacyclin
    Prostacyclin
    Prostacyclin is a member of the family of lipid molecules known as eicosanoids.As a drug, it is also known as "epoprostenol". The terms are sometimes used interchangeably.-History:...

  • thromboxane-A synthase
    Thromboxane-A synthase
    Thromboxane A synthase 1 , also known as TBXAS1, is an enzyme that, in humans, is encoded by the TBXAS1 gene.- Function :This gene encodes a member of the cytochrome P450 superfamily of enzymes...

     to create thromboxane A2
    Thromboxane A2
    Thromboxane A2 is a thromboxane. It is produced by activated platelets and has prothrombotic properties: it stimulates activation of new platelets as well as increases platelet aggregation. This is achieved by mediating expression of the glycoprotein complex GP IIb/IIIa in the cell membrane of...

  • prostaglandin D2 synthase
    Prostaglandin D2 synthase
    Prostaglandin-H2 D-isomerase is an enzyme that in humans is encoded by the PTGDS gene.-Further reading:...

     to create prostaglandin D2
    Prostaglandin D2
    Prostaglandin D2 is a prostaglandin that binds to the receptor PTGDR, as well as CRTH2. It is a major prostaglandin produced by mast cells – recruits Th2 cells, eosinophils, basophils. In mammalian organs, large amounts of PGD2 are found in the brain, in mast cells and found nowhere else...

  • Prostaglandin E synthase
    Prostaglandin E synthase
    Prostaglandin E synthase is an enzyme involved in eicosanoid and glutathione metabolism, a member of MAPEG family. It generates prostaglandin E from prostaglandin H2.The synthase generating PGE2 is a membrane-associated protein....
