肠内细菌参与了亚硝酸盐的还原... 吸收的亚硝酸盐在血液中通过哺乳动物过程迅速被氧化成硝酸盐... 硝酸盐生成过程与高铁血红蛋白(MetHb)的形成平行... 亚硝酸盐在吸收前也可能在胃中氧化成硝酸盐,如小鼠体内实验所示。然而,在体内条件下,亚硝酸盐可能在大量化硝酸盐形成之前从胃中被吸收。/亚硝酸盐/
... Intestinal bacteria were involved in the reduction of nitrite ... Absorbed nitrite is rapidly oxidized to nitrate in the blood by a mammalian process ... The process of nitrate generation parallels the methemoglobin (MetHb) formation ... Nitrite oxidation to nitrate may also occur in the stomach prior to absorption, as demonstrated in vitro for mice. However, under in vivo conditions, nitrite is probably absorbed from the stomach before large quantities of nitrate are formed. /Nitrite/
