omega-3 fatty acid

chemical compound

Quick Summary

Omega-3 fatty acids are a type of polyunsaturated fatty acid. They are characterized by having the final double bond in their hydrocarbon chain located between the third and fourth carbon atoms from the end of the molecule opposite the carboxyl group. These fatty acids are commonly found in sources such as fish, fish oils, green leafy vegetables, and certain nuts and vegetable oils.1

Fatty acids are essential components of many complex lipid molecules, including fats and phospholipids, which are crucial for energy storage and cellular membranes. Unsaturated fats, including omega-3s, are typically liquid at room temperature and are a concentrated source of energy. Consuming unsaturated fats over saturated fats can contribute to better heart health by helping to lower cholesterol levels.23
