WebMitochondrial fatty acid β-oxidation (FAO) is the major pathway for the degradation of fatty acids and is essential for maintaining energy homeostasis in the human body. Fatty acids are a crucial energy source in the postabsorptive and fasted states when glucose supply is limiting. But even when glucose is abundantly available, FAO is a main energy source for … Webβ-oxidation can be broken down into a series of steps. First, the fatty acid is activated. This involves the addition of a coenzyme A (CoA) molecule to the end of a long-chain fatty …
