Saturated fatty acids are defined as the fatty acids in which a single bond is present between carbon and carbon atoms and hydrocarbon chain is attached to carboxylic group. Example:

Unsaturated fatty acids are defined as the fatty acids which have double or triple covalent C-C bonds and hydrocarbon chain is attached to carboxylic group. Example:

Thus a saturated fatty acid has more hydrogens than unsaturated fatty acid.
