Which type of fats contain fatty acids with more than one double bond in the fatty acid chain?

Polyunsaturated fats are characterized by the presence of fatty acids that have two or more double bonds in their hydrocarbon chains. This structure allows them to remain liquid at room temperature and is important for various bodily functions, including brain health and the regulation of inflammation. Common sources of polyunsaturated fats include fish, walnuts, and flaxseeds, which provide essential fatty acids that the body cannot synthesize on its own, such as omega-3 and omega-6 fatty acids. Understanding the structure of these fats helps highlight their beneficial roles in a balanced diet, emphasizing the importance of incorporating them for overall health.
