%X lipidic pattern of 25 mexican marine fishes with special emphasis in their n-3 fatty acids as nutraceuticals components. the aim of this study was to characterize and to evaluate the lipidic composition of mexican marine fishes with special emphasis in n-3 fatty acids as nutraceuticals. the edible portion of 25 species: humidity (h), crude protein (cp), total lipids (tl) and fatty acids (fa). the average content (g/100g edible portion) of h was 75.20, pc was 18.40, tl was 3.60. four n-3 fa were identified in all the samples and they were found in the next abundance order (mg/100g edible portion): c22:6n-3 (dha)(229.60), c20:5 n-3 (epa)(52.10), c18:3 n-3 (ala)(11.80) and c20:3 n-3 (2.25). by their origin and climate there were no difference. by their biologycal classification, n-3 fa content was higher in bony fishes than cartilaginous fishes. it was detected a proportional relation with the n-3 fa concentration and total lipid content. according to their ecotic distribution there were numerical differences in dha content (mg/100g edible portion) between pelagics (420.70), benthopelagics (125.30) and demersals fishes (225.40). fatty fishes had higher content of epa and dha (mg/100g edible portion) (109.27 and 552.72) than semifatty fishes (56.12 and 226.29) and leanness (15.95 and 96.52), respectively. bony, fatty and pelagic fishes had a higher content of epa+dha. according with the international recommendation values (200 to 600 mg epa+dha/day) the 44% of the analyzed species could be considered as functional foods due to their high content of epa + dha in a range of 220 to 1300 mg/100g.
