Detailed explanation-1: -Fatty acids may be saturated or unsaturated. In a fatty acid chain, if there are only single bonds between neighboring carbons in the hydrocarbon chain, the fatty acid is said to be saturated. Saturated fatty acids are saturated with hydrogen since single bonds increase the number of hydrogens on each carbon.

Detailed explanation-2: -Saturated chains contain all single bonds, while the unsaturated ones have one (monounsaturated) or more (polyunsaturated) double bonds. The number of hydrogen atoms in the formula of an unsaturated structure will be less than that for the corresponding saturated one with the same number of carbon atoms.

Detailed explanation-3: -Saturated fatty acids contain no carbon-carbon double bonds, monounsaturated fatty acids contain one carbon-carbon double bond, and polyunsaturated fatty acids contain two or more carbon-carbon double bonds.

Detailed explanation-4: -If there are only single bonds between neighboring carbons in the hydrocarbon chain, a fatty acid is said to be saturated.
