Fatty acid metabolism refers to the biochemical processes that break down fatty acids to produce energy. This occurs primarily in the mitochondria of cells, where fatty acids are converted into acetyl-CoA through a process called β-oxidation. The resulting acetyl-CoA can then enter the Krebs cycle to generate ATP, the energy currency of the cell. In addition to energy production, fatty acid metabolism also plays a role in synthesizing important molecules, such as lipids and hormones. The balance between fatty acid breakdown and synthesis is crucial for maintaining overall metabolic health and supporting various bodily functions.
