4470 Creatinine Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. Creatinine is transferred to the kidneys by blood plasma, whereupon it is eliminated from the body by glomerular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate by the body. Measuring serum creatinine is a simple test and it is the most commonly used indicator of renal function. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. The typical reference range for women is considered about 45-90 umol/l, for men 60-110 umol/l. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas. 60-27-5 588 C4H7N3O White powder. 303°C (decomposes) 80.1 mg/mL at 16°C No indication of carcinogenicity to humans (not listed by IARC). This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions, catabolic reactions or waste generation. 2014-08-29T06:51:09Z 2026-04-14T18:26:08Z Creatinine C00791 16737 DB11846 true CN1CC(=O)NC1=N C4H7N3O InChI=1S/C4H7N3O/c1-7-2-3(8)6-4(7)5/h2H2,1H3,(H2,5,6,8) DDRJAANPRJIHGJ-UHFFFAOYSA-N 113.1179 113.058911861 Endogenous Solid -1.76 HMDB00562 CHEMBL65567 568 Reddick, Rebecca E.; Kenyon, George L.
