Metabolite Identification
Common NameProstaglandin I2
DescriptionProstaglandin i2, also known as prostaglandin I2 or prostaglandin I2, belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, prostaglandin I2 is considered to be an eicosanoid lipid molecule. Prostaglandin i2 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Prostaglandin i2 exists in all living organisms, ranging from bacteria to humans. Prostaglandin i2 participates in a number of enzymatic reactions, within cattle. In particular, Prostaglandin I2 can be converted into prostaglandin I2 through the action of the enzyme prostaglandin I2 receptor. In addition, Prostaglandin I2 can be converted into prostaglandin I2 through the action of the enzyme prostaglandin I2 receptor. In cattle, prostaglandin I2 is involved in the metabolic pathway called the intracellular signalling through prostaglandin I2 receptor and prostaglandin I2 pathway.
