Alpha-linolenic acid and docosahexaenoic acid are both classified as omega-3 fatty acids, which play a crucial role in human health. Alpha-linolenic acid (ALA) is a plant-based omega-3 fatty acid found in sources like flaxseeds, chia seeds, and walnuts. Docosahexaenoic acid (DHA) is primarily found in marine sources, such as fish and algae. Omega-3 fatty acids are known for their anti-inflammatory properties and beneficial effects on heart health, brain function, and overall well-being.

The choice of omega-3 fatty acids is supported by the fact that both ALA and DHA have distinct structural characteristics that define them as part of the omega-3 family, which is characterized by their first double bond located at the third carbon atom from the methyl end of the fatty acid chain. This specific arrangement is critical for their physiological functions.

In contrast, saturated fats lack double bonds in their fatty acid chains, which differentiates them from omega-3 fatty acids. Omega-6 fatty acids, while also essential, are a separate family with a different structural configuration involving their double bonds. Monounsaturated fats, on the other hand, feature a single double bond and
