From Wikipedia, the free encyclopedia. 12-Hydroxyeicosatetraenoic acid (12-HETE) is a derivative of the 20 carbon polyunsaturated fatty acid, arachidonic acid, containing a Hydroxyl residue at carbon 12 and a 5 Z, 8Z ,10 E ,14 Z Cisâtrans isomerism configuration (Z=cis, E=trans) in its four double bonds.n humans, Arachidonate 12-lipoxygenase (12-LO, 12-LOX, ALO12, or platelet type 12-lipoxygenase) is encoded by the ALOX12 gene and expressed primarily in platelets and skin.
Sulfuric acid in its pure form is a colorless viscous liquid commonly called oil of vitriol. The chemical formula for sulfuric acid is H 2 SO 4 and it is commercially available as a 96-98% solution or 18M H 2 SO 4. Concentrated sulfuric acid is covalent in nature as the acid is unionized. The atoms in the molecule are covalently bonded to one another. In this form sulfuric acid can be transported in stainless steel tankers. If concentrated sulfuric acid is added to water the reaction is extremely exothermic due to formation of hydrogen ions.
