* Monounsaturated fatty acids have only one unsaturated bond. Monounsaturated oils are liquid at room temperature but start to solidify at refrigerator temperatures. For example, salad dressing containing olive oil turns cloudy when refrigerated but is clear at room temperature.
So why do rape seed oil with same amount of monounsat fat don't cloud??
That's because squalene composition (which is the solidifying stuff in olive oil) is very different. Olive oil may be very high in squalenes, an important intermediate and precursor for cholesterol, while rape seed oil is high in phytosterols.
