General description

cis-5,8,11,14,17-Eicosapentaenoic acid belongs to the class of long-chain omega-3 polyunsaturated fatty acids. It is synthesized in the human body from the essential fatty acid alpha-linolenic acid.

Application

This analyticalstandard can also be used as follows:

  • Optimization of capillary zone electrophoresis procedurecoupled with direct absorption UV detection (CZE-UV) to determine eicosapentaenoicacid and docosahexaenoic acids after their methylation in 10 different samplesof commercial omega-3 supplements
  • Simultaneous determination of eicosapentaenoic acid,docosahexaenoic acid, and arachidonic acid in human plasma samples by high-performanceliquid chromatography-electrochemical detection (HPLC-ECD)
  • Separation, identification, and quantification of eicosapentaenoicacid, docosahexaenoic acid, and arachidonic acid in human plasma samples by high-performanceliquid chromatography combined with tandem mass spectrometry (HPLC-MS/MS)

Biochem/physiol Actions

5-Lipoxygenase inhibitor; reduces thromboxane A2 production.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
