- Liquid at room temperature
- One double bond in the form of two carbon atoms double-bonded to each other
- lack two hydrogen atoms
- kink or bend at the position of the double bond inhibiting packing together as easily as saturated fats
- therefore, tend to be liquid at room temperature
- Common Fatty Acids
- Oleic acid (18:1, Omega-9) is most common monounsaturated fat in food
- Palmitoleic acid (16:1, Omega-7)
- Cis-vaccenic acid (18:1, Omega-7)
- Erucic acid (22:1, Omega-9)
- Preferred in the diet
