Which fatty acid contains one double bond?

Monounsaturated fat is characterized by having one double bond in its fatty acid chain. This structural feature distinguishes it from saturated fats, which contain no double bonds, and polyunsaturated fats, which have multiple double bonds. The presence of a single double bond in monounsaturated fats gives them certain health benefits, such as improving heart health by potentially lowering bad cholesterol levels. Foods high in monounsaturated fats include olive oil, avocados, and nuts, all of which are associated with various health benefits.
