Fatty acids that do not have double bonds between carbons are called saturated fatty acids.

Here's why:

* Double bonds: Double bonds between carbon atoms create a kink in the fatty acid chain, making it less straight.

* Saturated: The term "saturated" refers to the fact that all the carbon atoms in the chain are bonded to the maximum number of hydrogen atoms possible. This leaves no room for double bonds.

Examples of saturated fatty acids include:

* Lauric acid (C12:0) found in coconut oil

* Myristic acid (C14:0) found in palm kernel oil

* Palmitic acid (C16:0) found in palm oil

* Stearic acid (C18:0) found in animal fats

In contrast, unsaturated fatty acids have one or more double bonds between carbon atoms.
