No, that statement is incorrect. Unsaturated fatty acids contain at least one double covalent bond between carbon atoms.

Here's why:

* Saturated fatty acids have all single bonds between carbon atoms, which means they are "saturated" with hydrogen atoms.

* Unsaturated fatty acids have at least one double bond between carbon atoms. This means they have fewer hydrogen atoms than a saturated fatty acid with the same number of carbon atoms. The presence of double bonds introduces a kink in the fatty acid chain, which affects its physical properties.

Let me know if you have any other questions.
