硝酸盐对人和动物的主要作用只知道其中Na~+和K~+引起的利尿作用,几乎不了解其它直接作用。然而,它是植物和微生物的重要氮源,与生物体有着密切的关系。从卫生化学看,亚硝酸盐的第一作用是使机体生成高铁血红蛋白的直接作用,它甚至会危及婴儿的生命。其次是生成N—亚硝基化合物的间接作用。致癌作用强而又广泛的N—亚硝基化合物,由亚硝酸盐同各种胺和酰脲化合物等反应,在体内和体外生成,所以近几年来将它作为重要的问题提出来。
The main role of nitrate on humans and animals only know the Na ~ + and K ~ + diuretic effect, almost no other direct effect. However, it is an important source of nitrogen for plants and microorganisms and has a close relationship with organisms. From the health chemistry, the first role of nitrite is to make the body produce a direct role of methemoglobin, it can even endanger the baby’s life. The second is the indirect effect of generating N-nitroso compounds. N-nitroso compounds, which have a strong carcinogenic effect and are extensively produced, are produced in vivo and in vitro by reacting nitrites with various amines and ureide compounds, etc., and have been proposed as important problems in recent years.
