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.
-(+)-lactic acid or (S)-lactic acid and the other, its mirror image, is. -(â)-lactic acid or (R)-lactic acid. A mixture of the two in equal amounts is called. -lactic acid. Lactic acid is hygroscopic. -lactic acid is miscible with water and with ethanol above its melting point which is around 17 or 18 Â°C.lactic acid have a higher melting point. In animals, -lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase (LDH) in a process of fermentation during normal metabolism and exercise.
