Summary : During the last few years, the physiological properties of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids have been investigated and beneficial effects can be attributed. EPA has been associated with a reduced risk of cardiovascular disease in adult, by altering platelet function towards a more anti‐atherogenic state. DHA is a major constituent of the neuronal structures including retina cell membranes. For populations at high risk of deficiency like new‐born babies and the elderly, diet must be supplemented with DHA. Therefore, these beneficial effects have promoted the development of dedicated preparations enriched either with EPA or DHA as long as bioavailability is needed in our diet. In this survey, the enzymatic methods to discriminate between EPA and DHA are reviewed.
