Lipoxygenases (LOXs) are a family of non-heme iron dioxygenases that are involved in the production and metabolism of fatty acid hydroperoxidases. There are six lipoxygenase isozymes; 5-LOX, 12R-LOX, 12S-LOX, 15-LOX-1, 15-LOX-2 and E-LOX.

Lipoxygenases (LOXs) are a family of non-heme iron dioxygenases that are involved in the production and metabolism of fatty acid hydroperoxidases. There are six lipoxygenase isozymes; 5-LOX, 12R-LOX, 12S-LOX, 15-LOX-1 and 15-LOX-2, which catalyze the regio-selective addition of oxygen into arachidonic acid, and epidermal LOX (E-LOX) which metabolizes 12R-hydroperoxyeicosatetraenoic acid (12R-HPETE) to a specific epoxyalcohol compound.
Different isozymes have different physiological roles; 5-, 12R-, 12S- and 15-LOX-1 have proliferative, antiapoptotic and angiogenic functions whilst 15-LOX-2 has roles in differentiation, growth arrest and the induction of apoptosis. E-LOX, the most divergent member of this family, is involved in terminal differentiation of keratinocytes and has a major role in skin barrier function. Perturbations in lipoxygenase enzymes have been implicated in various human diseases including bronchial asthma, atherosclerosis, osteoporosis and some cancers.
