Creatinine
Term
This is a cyclic compound, spontaneously formed from dephosphorylated creatine phosphate and excreted from the body in the urine. Creatinine is highly soluble in water, does not bind to proteins, and easily passes through the basal membrane of the renal nephron glomerulus, making its presence in urine useful for determining glomerular filtration function. The amount of creatinine excreted in the urine of each individual is constant and proportional to muscle mass.
