20. Beta-Oxidation: When Fat and Water Mix

In this lesson, we examine the beta-oxidation in its simplest form: the breakdown of a long-chain, saturated fatty acid. We see once again the principle that the oxygen content of a molecule determines how much water its metabolism consumes and how much carbon dioxide its metabolism releases. In beta-oxidation, we consume one water per round and release no carbon dioxide. This reflects the fact that fatty acids are not hydrates of carbons like sugars are, which is where the name carbohydrate comes from.
