Explanation:
Detailed explanation-1: -A fat molecule consists of two kinds of parts: a glycerol backbone and three fatty acid tails. Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.
Detailed explanation-2: -Humans can synthesize longer omega-6 and omega-3 fatty acids from the essential fatty acids linoleic acid (LA) and -linolenic acid (ALA), respectively, through a series of desaturation (addition of a double bond between two carbon atoms) and elongation (addition of two carbon atoms) reactions (Figure 3) (4, 5).
