A Fatty Acid contains a carboxyl ending [COOH] after a long hydrocarbon chain.
a. Saturated Fat - Has no double bonds
Ex. CH3 – CH2 – CH2 – CH2 – CH2 – COOH
b. Unsaturated Fat - Has double bonds
Ex. CH3 – CH2 – CH = CH – CH2 – COOH
Therefore, the difference between a saturated and unsatruated fats are double bonds.
