Fatty acids are carboxylic acids with a variable unbranched aliphatic tail (chain), which is either saturated or unsaturated. They are important as nutritional substances in living organisms. Long-chain polyunsaturated fatty acids (PUFA), especially those of the n-3 series, such as α-linolenic acid (18:3 n-3), are essential for human metabolism and have many beneficial effects including the prevention of a number of diseases, such as coronary heart diseases, inflammation, autoimmune disorders, hypertension, hypotriglyceridemic effects ( Bernal et al., 2011).
