Overview of Fatty Acid Oxidation

By: Khan Academy Medicine

This is a video that briefly explains how much energy fatty acids produce from fat in food. ATP is the energy that fatty acids produce in the body. About 95% of the chemical energy we can extract comes from carbon hydrogen chains that are referred to as fatty acid chains. The other 5% comes from glycerol. We extract ATP from fatty acid chains by oxidation. We extract  the electrons and transfer them to an electron carrier, this produces nadh and fadh2 which are able to use ATP in electron transport chains. This is essentially the reverse of fatty acid synthesis. As we break down the hydrogens and carbons we are oxidizing them to release energy. Breaking up the large fatty acids make acetyl co a. Acetyl co a then enters the Krebs cycle in the mitochondria which produces energy as well as making more electron carrier molecules nadh and fadh2 which is more energy. Fatty acids produce more energy compared to glycerol.
