urea synthesis

Urea synthesis is a biological process in the liver where the body removes excess nitrogen from proteins we eat. When our body breaks down amino acids, it produces nitrogen waste that can be harmful if accumulated. The liver converts this nitrogen into a safer compound called urea, which dissolves in blood and is carried to the kidneys. The kidneys then filter urea out of the blood and eliminate it through urine. This process, known as the urea cycle, helps maintain the body's nitrogen balance and prevents toxic buildup.
