Monounsaturated fatty acids
Abbreviations
- MUFA
- 1UFA
Synonyms
- Monounsaturated Fats, Monoenoic fatty acids
Description
Represents the sum of all fatty acids that contain exactly one double bond in their hydrocarbon chain (e.g., oleic acid C18:1, palmitoleic acid C16:1).
Nutritional potential:
In human nutrition, MUFAs are widely recognized as healthy dietary fats. Replacing saturated fats with MUFAs helps lower low-density lipoprotein (LDL) cholesterol levels while maintaining or even increasing high-density lipoprotein (HDL) cholesterol, thereby reducing the risk of cardiovascular diseases. They also play a role in improving insulin sensitivity and reducing systemic inflammation.
Biodiesel potential:
In fuel applications, MUFAs provide an optimal balance between cold flow properties and oxidation stability. Compared to saturated fatty acids, they have lower melting points, which improves the cold filter plugging point (CFPP) and overall cold-weather performance. Compared to polyunsaturated fatty acids (PUFA), they are significantly less prone to oxidation and offer a better cetane number (CN). Feedstocks rich in MUFA (such as high-oleic oils) are considered highly desirable for high-quality biodiesel production.
