<p>Importing a new version from external source</p> <p><b>New page</b></p><div>===Degradation===<br /> [[Beta oxidation]] is the metabolic process by which fatty acids are broken down in the [[mitochondria]] or in [[peroxisomes]] to generate [[acetyl-CoA]]. For the most part, fatty acids are oxidized by a mechanism that is similar to, but not identical with, a reversal of the process of fatty acid synthesis. That is, two-carbon fragments are removed sequentially from the carboxyl end of the acid after steps of [[dehydrogenation]], [[hydration reaction|hydration]], and [[oxidation]] to form a [[keto acid|beta-keto acid]], which is split by [[thiolysis]]. The acetyl-CoA is then ultimately converted into [[adenosine triphosphate]] (ATP), CO&lt;sub&gt;2&lt;/sub&gt;, and H&lt;sub&gt;2&lt;/sub&gt;O using the [[citric acid cycle]] and the [[electron transport chain]]. Hence the citric acid cycle can start at acetyl-CoA when fat is being broken down for energy if there is little or no glucose available. The energy yield of the complete oxidation of the fatty acid palmitate is 106 ATP. Unsaturated and odd-chain fatty acids require additional enzymatic steps for degradation.</div>
