Why do animals require lipids for normal physiological function? While animals can produce some fatty acids on their own (de novo), others must be acquired from the diet
Which are the two essential fatty acids that animals cannot manufacture themselves, and what are their sources?
Answer: Animals require lipids for a variety of functions, including phospholipids to build cell membranes, triglycerides to provide metabolic energy, and other lipids to serve in cell signaling.
Animals cannot manufacture omega-6 (linoleic acid) and omega-3 (alpha-linolenic acid) fatty acids, and therefore need to obtain both from their diet. Fish is the best source of omega-3 fatty acids, while plant seeds are high in omega-6 fatty acids.
