One of the ways to differentiate between unsaturated and saturated fats is by comparing their chemical structures. When you consider the chemical structures of most saturated fats, they are usually marked by the absence of double bonds between their carbon atoms, whereas the opposite is the case for unsaturated fats because there is the presence of double bonds in their carbon atoms.
Another difference between the two is their physical state at room temperature. While saturated fats are usually solid at room temperature, unsaturated fats are liquid. Both saturated fats and unsaturated fats contribute to the cholesterol level of the body, but saturated fats are most times considered as harmful to the body because they cause the LDL cholesterol level of the body to increase.
In contrast, unsaturated fats are very needed in the body. Examples of unsaturated fats are canola oil, olive oil, sunflower oil, etc. Examples of saturated fats are red meat, butter, chicken fat.
