Active
Term Description
"Carnitine" is an alternative way to say total carnitines which = free carnitine + acylcarnitines, or stated another way, unesterified + esterified carnitine.

Part Descriptions
LP14482-1 Carnitine
Carnitine is used to mean total carnitines, because historically total carnitine was measured by heating up the sample and breaking off the esters which provided pure carnitine. (Carnitine is also a single molecule which is described as free carnitine - with the acronym, C0). Aclycarnitine is not a single moiety but rather describes all of the esterified carnitines.
So Total carnitine = free carnitine(C0) + acylcarnitine = esterified + unesterified carnitine.

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.
