Chemical Synthesis	Corey_EJ et al.
Metabolism	When arachidonic acid is oxygenated by 12-lipoxygenase, 12(S)-hydroperoxy-5,8,10,14-(Z,Z,E,Z)-eicosatetraenoic acid is produced Yamamoto_S et al.. The latter compound is reduced to a corresponding 12(S)-hydroxy acid with whole cells or crude enzyme preparations.
Biological Activity	There are reports for various biological activities of 12(S)-hydroxy acid such as rat hypothalamic secretion of LH-RH, stimulated chemotactic activity of human eosinophils and neutrophils, stimulated migration of epidermal tumor cells and rat aortic smooth muscle cells, involvement in angiotension II-mediated aldosterone biosynthesis in human adrenal glomerulosa, and expression or activation of GpIIb/IIIa in tumor cells, but a general theory has not been established Yamamoto_S et al. Yoshimoto_T et al..
