Part Descriptions
LP15721-1 Malonate
The malonate or propanedioate ion is CH2(COO)22− (malonic acid minus two hydrogen ions). Malonate compounds include salts and esters of malonic acid, such as diethyl malonate, (C2H5)2(C3H2O4), dimethyl malonate, (CH3)2(C3H2O4), disodium malonate, Na2(C3H2O4). Malonate is an inhibitor of cellular respiration, because it binds to the active site of the succinate dehydrogenase in the citric acid cycle but does not react, thereby competing with succinate. For the oxidative phosphorylation reaction, Malonate is an inhibitor for complex II which, again, contains succinate dehydrogenase.

LP32035-5 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. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. 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. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
