Chemical Information
NameUrea
DescriptionUrea, also known as ur or carbamide, belongs to the class of organic compounds known as ureas. Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group. Urea is an extremely weak basic (essentially neutral) compound (based on its pKa). Urea exists in all living species, ranging from bacteria to humans. Within humans, urea participates in a number of enzymatic reactions. In particular, urea can be converted into urea through the action of the enzyme urea transporter 2. In addition, urea can be converted into urea; which is mediated by the enzyme urea transporter 2. In humans, urea is involved in torsemide action pathway. Outside of the human body, Urea is found, on average, in the highest concentration within milk (cow). Urea has also been detected, but not quantified in, several different foods, such as thistles, kai-lans, red raspberries, biscuits, and black crowberries. This could make urea a potential biomarker for the consumption of these foods. Urea is a potentially toxic compound. A carbonyl group with two C-bound amine groups.
