Metabolite Identification
Common NameEthanolamine Oleate
DescriptionEthanolamine Oleate is only found in individuals that have used or taken this drug. It is a mild sclerosing agent. It is composed of ethanolamine, a basic substance, which when combined with oleic acid forms a clear, straw to pale yellow colored, deliquescent oleate.The oleic acid component of ethanolamine oleate is responsible for the inflammatory response, and may also activate coagulation in vivo by release of tissue factor and activation of Hageman factor. The ethanolamine component, however, may inhibit fibrin clot formation by chelating calcium, so that a procoagulant action of ethanolamine oleate has not been demonstrated.

General function:
Involved in monooxygenase activity

General function:
Involved in serine-type endopeptidase activity
Specific function:
Factor XII is a serum glycoprotein that participates in the initiation of blood coagulation, fibrinolysis, and the generation of bradykinin and angiotensin. Prekallikrein is cleaved by factor XII to form kallikrein, which then cleaves factor XII first to alpha-factor XIIa and then trypsin cleaves it to beta- factor XIIa. Alpha-factor XIIa activates factor XI to factor XIa
