产品描述

尿素参与含氮物质的代谢。 当用于肥料时,它可作为氮源。 尿素用于制造化合物。 它在农业中广泛用作肥料和动物饲料添加剂,在畜牧业中用作氮的补充。 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。

General description

Urea is a colourless organic compound, without any odour. It is easily soluble in water.[1]

Application

Urea has been used:
• to adjust the urea nitrogen concentration to a preferred range in blood reservoir for evaluating the dialyzer urea clearance[4]
• to prepare standards to measure urea synthesis[5]
• to prepare standards for blood urea nitrogen assay[6]
尿素已被使用:
•将血液中的尿素氮浓度调整到优选范围,以评估透析器的尿素清除率
•制定衡量尿素合成的标准
•准备血液尿素氮测定标准

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

Urea participates in the metabolism of nitrogenous substances. It serves as a nitrogen source, when used in fertilizers. Urea is used in manufacturing chemical compounds.[1] It is widely used in the agricultural industry as a fertilizer as well as an animal feed additive, which is used as a nitrogen supplement in animal husbandry.[3] Urea has adverse effects on seed germination, seedling growth and early plant growth in soil.[2]
