LEVELS OF N-3, N-6 POLYUNSATURATED FATTY ACIDS AND SERUM CHOLESTEROL IN FISH FROM DIFFERENT AQUATIC HABITATSM. NAGABHUSHAN REDDY AND MD. BASHA MOHIDEENAbstract
Fish and other marine life are rich sources of polyunsaturated fatty acids known as omega-3 or n-3 fatty acids. Fish with higher levels of n-3 polyunsaturated fatty acids and lower levels of serum cholesterol has important role in reducing coronary heart diseases. Marine fish, mackerel showed significantly higher levels of n-3 polyunsaturated fatty acids - alphalinolenic acid, eicosapentaenoic acid, docosahexaenoic acid and lower levels of both serum cholesterol and n-6 polyunsaturated fatty acids -arachidonic acid, linoleic acid when compared to brackish water fish, mullet and freshwater fish catla, rohu and mrigal. The levels of different types of n-3 polyunsaturated fatty acids and n-6 polyunsaturated fatty acids in fish from different aquatic habitats were in the order: mrigal |
