What type of fatty acid contains multiple double bonds?

Polyunsaturated fat is characterized by the presence of multiple double bonds in its fatty acid chains. This structure allows for the unique properties and functions of polyunsaturated fats in the body. These fats are divided into two main categories based on their double bond configurations: omega-3 and omega-6 fatty acids, both of which play crucial roles in maintaining cell membrane integrity, regulating inflammation, and supporting heart health.

In contrast, saturated fatty acids contain no double bonds, while monounsaturated fats contain only one double bond. Trans fats are a type of unsaturated fat with a specific configuration that can arise from industrial processing, but they do not have the multiple double bonds found in polyunsaturated fats. Therefore, the defining feature of polyunsaturated fats is their multiple double bonds, which significantly influence their nutritional benefits and metabolic effects in the human body.
