The respiratory decomposition of fatty acids is known as beta oxidation, which occurs in liver and adipose tissue. Activation of fatty acids takes place, then dehydrogenation of activated fatty acid takes place. It is followed by hydration. The $β$ -hydroxyl acyl derivative is converted to $β$ -keto derivative, which then reacts with Co-A. And it leads to oxidation.
