Fish oil is an industrial product with significant nutritional value, Because it contains long-chain omega-3 polyunsaturated fatty acids, like docosahexaenoic acid (DHA), docosapentaenoic acid, and eicosapentaenoic acid (EPA), which are currently highly valued for their preventative and therapeutic properties in the nutritional and health fields, Data on the composition of fatty acids are obtained through qualitative examination of fatty acids and are presented as percentages of all fatty acids (% of total fatty acids). The body transforms the major omega-3 fatty acid, Alpha-linoleic acid, into the fatty acids EPA and DHA. With a ratio of 1.325 to 2.567, the high quantities of unsaturated fatty acids and low levels of saturated fatty acids imply that the oils and fatty acids have low cholesterol levels overall. EPA: Long-chain fatty acids with a long, unbranched aliphatic tail (chain) of saturated or unsaturated carboxylic acid are the source of eicosapentaenoic acids (20:5n-3). DHA: Long-chain fatty acids having a long, unbranched aliphatic tail (chain) of fatty Acid.
