General description
尿素是无色有机化合物,无任何异味。它易溶于水。
Application
尿素已用于:
- 将储血罐中的尿素氮浓度调节至优选范围,以评估透析器尿素清除率
- 制备测量尿素合成的标准品
- 制备用于血液尿素氮测定的标准品
用于蛋白质变性以及作为不溶性或变性蛋白的温和增溶剂。可用于从已由 6M 盐酸胍变性的样品(如包涵体)复性蛋白质。可与盐酸胍和二硫苏糖醇 (DTT) 一起用于复性变性蛋白以恢复其天然或活性形式。
Biochem/physiol Actions
尿素参与含氮物质的代谢。用作肥料时,它可作为氮源。尿素用于制造化合物。它在农业领域广泛用作肥料和动物饲料添加剂,在畜牧业中用作氮补充剂。尿素会对土壤中的种子发芽、幼苗生长和植物早期生长产生不利影响。
