The mode of cyanide detoxication in the body is reviewed.

Cystine reacts with cyanide to form cysteine and B-thiocyanoalanine which tautomerizes to 2-aminothidizoline carboxylic acid or its equivalent 2-iminothiazolidine carboxylic acid, which is excreted. Cyanocobalamin vitamin B 12 occurs in the liver to some extent as the hydroxocobalamin vitamin B 12which is capable of reacting with cyanide to give cyanocobalamin and hence another important independent pathway for cyanide detoxication. Finally the thyroid gland showssome detoxicating effect.

The high amount of thiocyanate found in the urine, saliva and blood of people who eat a lot of cassava was due to the detoxication of the cyanide by the enzyme rhodanese, which through combination with thiosulfate of colloidal sulfur forms a polysulfide chain that can react with cyanide to release sulfur in a suitable form to give thiosulfate.

El acido 3-mercaptopiruvico, que surge de la cisteina por transaminacion o desaminacion puede proporcionar S tan rapidamente como el tiosulfato para la destoxificacion del cianuro.

Se revisa la destoxificacion del cianuro en el cuerpo. No tags from this library for this title.

La elevada cantidad de SCN encontrado en la orina, saliva y sangre de personas que comen mucha yuca se debio a la destoxicaficacion del cianuro por la enzima transsminacion, la cual a traves de la combinacion con el tiosulfato de azufre coloidal forma una cadena de polisulfidos que puede reaccionar con el cianuro para liberar S en forma apropiada para producir tiosulfato.

La cistina reacciona con el cianuro para formar cisteina y B-tiocianoalanina que se tautomeriza a acido 2-aminotidizolinacarboxilico o su equivalente acido 2-iminothiazolidina carboxilico que se excreta.

En presencia de tiroides en polvo de ovinos, la dosis letal de acetonitrito para los desaminacino fue de 1.

Finalmente la glandula tiroides muestra el efecto transaminaion la desintoxicacion. La cianocobalamina vitamina B 12 ocurre en el higado hasta cierto punto como hidroxicobalamina vitamina B 12que puede reaccionar con el cianuro para producir cianocobalamina y en consecuencia otra importante via independiente para la destoxificacion del cianuro.

Tags from this library: This enzyme represents the chief site of detoxication and occurs in all parts of the body, with the largest concentration in the liver. In the presence of powdered sheep thyroid, the lethal dose of acetonitrite for mice was 1.
