Briefly, (3-carboxypropyl)trimethyl(d 9 )ammonium chloride (d 9 -butyrobetaine chloride, d 9 -BB) was prepared from -aminobutyric acid in methanol with potassium hydrogen carbonate and d 3 -methyl iodide (all from Sigma-Aldrich) (63)
Pharmacokinetics: Cyanocobalamin is administered intranasally, orally, and parenterally, while hydroxocobalamin is administered only parenterally. Once absorbed, vitamin B12 is highly bound to transcobalamin II, a specific B-globulin carrier protein and is distributed and stored primarily in the liver as coenzyme B12. The bone marrow also stores a significant amount of the absorbed vitamin B12. This vitamin crosses the placenta and is distributed into breast milk. Enterohepatic recirculation conserves systemic stores. The half-life is about 6 days (400 days in the liver). Elimination is primarily through the bile; however, excess cyanocobalamin is excreted unchanged in the urine
