Which fatty acid contains no double bonds?

Saturated fat is characterized by the absence of double bonds between its carbon atoms. This means that all carbon atoms in the fatty acid chain are "saturated" with the maximum number of hydrogen atoms possible. As a result, saturated fats tend to be solid at room temperature and are commonly found in animal products, as well as some plant oils.

In contrast, monounsaturated fats contain one double bond, while polyunsaturated fats contain two or more double bonds. Trans fats are artificially created through hydrogenation, which can lead to some trans configurations, but they also don’t fit the definition of containing zero double bonds consistently in their structure.

Thus, the defining characteristic of saturated fats is their lack of double bonds, distinguishing them from the other options.
