Metilkobalamin (mekobalamin, MeCbl, ili MeB₁₂) je kobalamin koji se koristi u tretmanu periferne neuropatije, dijabetičke neuropatije, i kao preliminarni tretman za amiotrofičnu lateralnu sklerozu. On je forma vitamina B₁₂ i razlikuje se od cijanokobalamina po tome što je cijanid zamenjen metil grupom.^[4] Metilkobalamin poseduje oktaedralni centar kobalta(III). Metilkobalamin se može dobiti u obliku svetlih crvenih kristala.^[5]

Iz perspektive koordinacione hemije, metilkobalamin je osoben po tome što je redak primer enzima koji sadrži metal-alkil veze. Nikal-metil intermedijeri su predloženi kao mogući završni korak metanogeneze.

Produkcija

Metilkobalamin se može formirati u laboratoriji redukcijom cijanokobalamina sa natrijum borohidridom u alkalnom rastvoru, i naknadnom adicijom metil jodida.^[5]
