WebMar 23, 2024 · 1. Figure 17.2. 1: α and β carbons of fatty acids. This pathway is called β-oxidation. Fatty acids containing double bonds and those containing a 2-methyl branch at carbon 2 are oxidized in a step-wise fashion by this pathway. In each repetitive cycle of this pathway, acetyl-CoA and one CO 2 are released. WebThe beta oxidation of fatty acids occurs by the removal of two carbons at a time as acetyl CoA in a spiral type reaction. These reactions occur in the mitochondria and thus are closely associated with the electron transport … codinwar
