OCTN2 has a high affinity for carnitine and sodium ions (Na+) and readily binds to both and so carnitine is transported into skeletal muscle against a substantial concentration gradient via a transport process involving sodium Na+ flow
Vitamin B-12 is the source of coenzymes for the respective methylation of homocysteine by 5-methyltetrahydrofolate (5-methylTHF) to form methionine and for the mitochondrial conversion of methylmalonyl-CoA to succinyl-CoA ( Figure 1 )
