Scientific research provides documented evidence that fatty acid, metabolites have profound impact on carcinogenesis. Intervention into, dioxygenase pathways might therefore effect development, metastasis and, progression of many types of cancers. This work delivers the first 3D, structural data and explains how curcumin interacts with the fatty acid, metabolizing enzyme, soybean lipoxygenase. Curcumin binds to lipoxygenase, in a non-competitive manner. Trapped in that complex, it undergoes, photodegradation in the X-rays, but utilizes enzyme catalytic ability to, form the peroxy complex Enz-Fe-O-O-R as 4-hydroperoxy-2-methoxy-phenol, that later transforms into 2-methoxycyclohexa-2,5-diene-1,4-dione. Our, observations about this radiation and time-dependent inhibition add new, information to the role that curcumin might play in cancer prevention and, treatment.

== Function ==
 +
[https://www.uniprot.org/uniprot/LOX3_SOYBN LOX3_SOYBN] Plant lipoxygenase may be involved in a number of diverse aspects of plant physiology including growth and development, pest resistance, and senescence or responses to wounding. It catalyzes the hydroperoxidation of lipids containing a cis,cis-1,4-pentadiene structure.
