Description

Application

Isobutyryl-L-carnitine may be used as an analytical reference standard for the separation and identification of underivatized isobutyryl-L-carnitine in human plasma samples using high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS).[1] It may also be used as an analytical reference standard for the quantification of the analyte in human urine samples using liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS).[2]

General description

Isobutyryl-L-carnitine belongs to the acylcarnitines class of compounds.[1] These compounds are produced from L-carnitine, which plays an important role in fatty acid metabolic pathways. The functions and roles of acyl-L-carnitines in various tissues like brain, heart, and muscle continue to attract much interest.
