Which type of fatty acid has a kink due to cis double bonds?
Understand the Problem
The question is asking about the specific type of fatty acid that contains a kink in its structure due to the presence of cis double bonds. This refers to the geometry of the fatty acid molecules, specifically how the shape changes with different types of bonding.
Answer
Cis unsaturated fatty acids have a kink due to cis double bonds.
Fatty acids with a cis configuration have a kink due to the cis double bonds.
Answer for screen readers
Fatty acids with a cis configuration have a kink due to the cis double bonds.
More Information
Cis double bonds create a bend or kink in the fatty acid chain because the hydrogen atoms are positioned on the same side of the double-bonded carbon atoms. This structural difference impacts the physical properties of the fatty acid, such as how tightly the molecules can pack together.
Tips
A common mistake is confusing cis double bonds with trans double bonds. Trans double bonds do not cause a kink in the fatty acid chain.
