Hydroxo-Cobalaminとは 意味・読み方・使い方

Hydroxocobalamin (OHCbl, or B_12a) is a natural form, or vitamer, of vitamin B12, a basic member of the cobalamin family of compounds. Hydroxocobalamin is the form of vitamin B₁₂ produced by many bacteria which are used to produce the vitamin commercially. Like other forms of vitamin B₁₂, hydroxocobalamin has an intense red color. It is not a form normally found in the human body, but is easily converted in the body to usable coenzyme forms of vitamin B₁₂. Pharmaceutically, hydroxycobalamin is usually produced as a sterile injectable solution, and is used for treatment of the vitamin deficiency, and also (because of its afinity for cyanide ion) as a treatment for cyanide poisoning. Experimentally, it has been tested as a scavenger of nitric oxide.
