Final answer:
Saturated fats have no carbon-to-carbon double bonds and all carbons are bonded to as many hydrogen atoms as possible, making them saturated with hydrogen.
Step-by-step explanation:
If a fat is saturated, this means that there are no carbon-to-carbon double bonds (C=C) in the molecule, and all of the carbons (except for the acid group carbon) are bonded to as many hydrogen atoms as possible. These types of fats are termed saturated with hydrogen. Therefore, besides being bonded to the carbon next to it, all of the carbons' other bonds are with hydrogen. Saturated fats, like stearic acid, tend to be solid at room temperature and are often found in animal products.
