代谢
...对小鼠注射丙酮氰醇...在大脑和肝脏中产生了与氰化钠相似的氰化物浓度;肝脏中氰化物的浓度始终高于大脑中发现的浓度。...即使在高度纯净的体外条件下,丙酮氰醇也能迅速且完全地分解为其摩尔当量的自由氰化物。...来自丙酮氰醇的氰化物通过肝脏的硫氰酸酶代谢,后者介导氰化物转化为毒性小得多的硫氰酸盐,最终出现在尿液中。
The injection of acetone cyanohydrin in mice ... produced similar concentrations of cyanide in brain and liver /as that of sodium cyanide/; liver consistently contained higher concentrations of cyanide than those found in brain. ... Acetone cyanohydrin was promptly and completely dissociated into its molar equivalent in free cyanide, even under highly purified in vitro conditions. ... The cyanide rising from acetone cyanohydrin is metabolized by hepatic rhodanese which mediates the conversion of cyanide to the far less toxic thiocyanate that ultimately appears in the urine.
