What are monounsaturated fatty acids (MUFAs) classified as?

Monounsaturated fatty acids (MUFAs) are classified as unsaturated fatty acids due to their chemical structure, which includes one double bond in their fatty acid chain. This double bond causes the fatty acid to be less saturated with hydrogen atoms, distinguishing it from saturated fats that contain no double bonds and are fully saturated with hydrogen.

MUFAs are typically found in various healthy foods, including olive oil, avocados, and certain nuts, and are known to contribute to heart health by helping to lower bad cholesterol levels. This classification as unsaturated fatty acids is significant because it indicates beneficial properties associated with these fats compared to saturated fats and trans fats, which can raise cholesterol levels and are associated with various health risks. Cholesterol, on the other hand, is a sterol compound and not classified as a fatty acid, further emphasizing the unique position of MUFAs in the context of dietary fats and nutrition.
