So beta-oxidation is a proces in which fatty acids are broken down and results in two molecules, where one is Acetyl-CoA. However, if I look at the the scheme of beta-oxidation, I don't understand which is/are the fatty acids in this process. So for example, Acyl-CoA will eventually result in myristoyl-CoA and Acetyl-CoA. What is the fatty acid in this beta-oxidation process?
