Part Description

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. Source: Regenstrief Help
