oxidative phosphorylation
once inside the mitochondria, each cycle of β-oxidation, liberating a two carbon unit (acetyl-coa), occurs in a sequence of four reactions:









































this process continues until the entire chain is cleaved into acetyl coa units. the final cycle produces two separate acetyl coas, instead of one acyl coa and one acetyl coa. for every cycle, the acyl coa unit is shortened by two carbon atoms. concomitantly, one molecule of fadh, nadh and acetyl coa are formed.

beta oxidation
the pyruvate produced by glycolysis is an important intermediary in the conversion of carbohydrates into fatty acids and cholesterol. this occurs via the conversion of pyruvate into acetyl-coa in the mitochondrion. however, this acetyl coa needs to be transported into cytosol where the synthesis of fatty acids and cholesterol occurs. this cannot occur directly. to obtain cytosolic acetyl-coa, citrate (produced by the condensation of acetyl coa with oxaloacetate) is removed from the citric acid cycle and carried across the inner mitochondrial membrane into the cytosol. there it is cleaved by atp citrate lyase into acetyl-coa and oxaloacetate. the oxaloacetate is returned to mitochondrion as malate (and then converted back into oxaloacetate to transfer more acetyl-coa out of the mitochondrion). the cytosolic acetyl-coa is carboxylated by acetyl coa carboxylase into malonyl coa, the first committed step in the synthesis of fatty acids.
