Which one of the following is an abnormal constituent of urine ? A)Creatinine B)Urea C)Uric acid D)Ketone bodies
Option D) Ketone bodies are three water-soluble compounds that are produced as by-products when fatty acids are broken down for energy in the liver. Two of the three are used as a source of energy in the heart and brain while the third is a waste product excreted from the body. When the rate of synthesis of ketone bodies exceeds the rate of utilization, their concentration in blood increases, this is known as ketonemia. This is followed by ketonuria- excretion of ketone bodies in urine.
