Saturated Fatty Acids:

A saturated fat is a fat in which the fatty acidsall have single bonds. Double bonds can react with hydrogen to form single bonds. They are called saturated, because the second bond is broken up and each half of the bond is attached to (saturated with) a hydrogen atom. Most animal fats are saturated.

List of unsaturated fatty acids

Unsaturated Fatty Acids:

Unsaturated fats are fats or fatty acids that are liquid a room temperature. Unsaturated fats are derived from plants and some animals. They contain at least one double bond in their fatty acid chain. Conversely, a saturated fat has no double bonds meaning it is saturated with hydrogen atoms.
