12-Hydroxy Lauric Acid-d20

13(S)-HODE

13(S)-HOTrE

13(S)-HOTrE is the 15-lipoxygenase (15-LO) product of linolenic acid. It has been detected in cell membranes and as the cholesteryl ester associated with the lesions of atherosclerosis, and in the biomembranes of soybeans exposed to 15-LO.

13(S)-HPODE

13(S)-HPODE is a hydroperoxide formed from the oxidation of linoleic acid shown to inhibit platelet aggregation.

13(S)-HpOTrE

13(S)-HpOTrE is a monohydroperoxy polyunsaturated fatty acid produced in soybeans by the action of soybean LO-2 on esterified α-linolenic acid. Incubation of soybean seedling biomembranes with soybean LO-2 catalyzes the formation of both 9-?and 13-HpOTrE in a molar ratio of 10:1.?In plants, 13(S)-HpOTrE can be metabolized by the hydroperoxide lyase pathway producing aldehyde and oxoacid fragments, or by the hydroperoxide dehydratase pathway producing jasmonic acid. Treatment of tomato leaves with 13-HpOTrE causes induction of proteinase inhibitors, simulating the normal response to wounding. This data suggests that in plants 13(S)-HpOTrE may participate in a lipid-based signalling system initiated by insect and pathogen attack.

13-O-Methyl Amphotericin B

Impurity in commercial preparations of Amphotericin.

13-cis Acitretin

A synthetic retinoid which is the major metabolite of etretinate.
