Cyanocobalamin is a form of vitamin B 12 used to treat and prevent vitamin B 12 deficiency except in the presence of cyanide toxicity. [7] [8] [2] The deficiency may occur in pernicious anemia, following surgical removal of the stomach, with fish tapeworm, or due to bowel cancer.

Hydroxocobalamin, a form (or vitamer) of vitamin B 12 made by bacteria, and sometimes denoted vitamin B 12a, is used to bind cyanide to form the harmless cyanocobalamin form of vitamin B 12. 4-Dimethylaminophenol: 4-Dimethylaminophenol (4-DMAP) has been proposed [by whom?] in Germany as a more rapid antidote than nitrites with (reportedly ...
Cyanocobalamin is a manufactured form of B 12. Bacterial fermentation creates AdoB 12 and MeB 12, which are converted to cyanocobalamin by the addition of potassium cyanide in the presence of sodium nitrite and heat. Once consumed, cyanocobalamin is converted to the biologically active AdoB 12 and MeB 12. [citation needed] The two bioactive ...
Pernicious anemia is a disease where not enough red blood cells are produced due to a deficiency of vitamin B 12. [5] Those affected often have a gradual onset. [5] The most common initial symptoms are feeling tired and weak. [4]
Hydroxocobalamin has a higher affinity to the TC II transport protein than cyanocobalamin, or adenosylcobalamin. From a biochemical point of view, two essential enzymatic reactions require vitamin B 12 (cobalamin). [21] [22] Intracellular vitamin B 12 is maintained in two active coenzymes, methylcobalamin and adenosylcobalamin.

Removal of cyanide from cassava in Nigeria. Cyanides are produced by certain bacteria, fungi, and algae.It is an antifeedant in a number of plants. Cyanides are found in substantial amounts in certain seeds and fruit stones, e.g., those of bitter almonds, apricots, apples, and peaches. [5]
