Unsaturated

Definition

Unsaturated fats contain at least one double bond within the fatty acid chain, resulting in fewer hydrogen atoms. They are typically liquid at room temperature and found in plant oils and fish.

5 Must Know Facts For Your Next Test

1. Unsaturated fats can be divided into monounsaturated and polyunsaturated fats based on the number of double bonds.
2. Monounsaturated fats have one double bond, while polyunsaturated fats have two or more.
3. Unsaturated fats are generally considered healthier than saturated fats as they can help reduce cholesterol levels.
4. Common sources of unsaturated fats include olive oil, avocados, nuts, and certain types of fish.
5. The presence of double bonds causes kinks in the fatty acid chains, preventing them from packing tightly together.
