Free carnitine urinary excretion during childhood [PDF]

Pediatric Research, 1980
Free carnitine excretion in urine was measured in 86 healthy children aged 1 day to 10 years in order to establish a pattern during development.In 30 of these cases the data were subdivided into day/ night period.Nine children were also followed over 3 consecutive days.The radiochemical method of Cederblad and Lindstedt was used for free carnitine ...

Free L‐carnitine in human seminal plasma [PDF]

International Journal of Andrology, 1981
It has often been suggested that determination of free L(—)‐carnitine in seminal plasma may provide a good indication of epididymal function. However, there has been disagreement regarding the origin of L(—)‐carnitine (epididymis and seminal vesicles) and its concentration in human seminal plasma. In this study, free L(—)‐carnitine was determined after

Free carnitine and branched chain amino acids are not good biomarkers in Huntington’s disease [PDF]

Arquivos de Neuro-Psiquiatria, 2020
Background: Huntington’s disease (HD), caused by an expanded CAG repeat at HTT, has no treatment, and biomarkers are needed for future clinical trials. Objective: The objective of this study was to verify if free carnitine and branched chain amino acids ...

Free and esterified carnitine in continuous ambulatory peritoneal dialysis patients

Kidney International, 1996
Free, acetyl-, medium- and long-chain acylcarnitine and total plasma carnitine concentrations were measured in eight continuous ambulatory peritoneal dialysis (CAPD) patients and eight age- and sex-matched healthy controls. Daily loss of carnitine was also quantified in both groups, by analysis of urine and dialysis fluid.

Evaluation of free and bound carnitine in young athletes

Rossiyskiy Vestnik Perinatologii i Pediatrii (Russian Bulletin of Perinatology and Pediatrics), 2023
The study of the characteristics of carnitine metabolism in representatives of certain sports makes it possible to study the effect of physical loads of various nature on the body of a young athlete, and also makes it possible to assess the competitive potential and predict the tolerance of long-term and intense loads. Purpose.

Structural basis of sodium ion-dependent carnitine transport by OCTN2 [PDF]

Nature Communications
Carnitine is essential for the import of long-chain fatty acids into mitochondria, where they are used for energy production. The carnitine transporter OCTN2 (novel organic cation transporter 2, SLC22A5) mediates carnitine uptake across the plasma ...

Enzymatic determination of free carnitine in milk and infant formulas.

Journal of AOAC INTERNATIONAL, 1995
Abstract A simple spectrophotometric assay for free carnitine in milk and supplemented infant formulas has been developed. After acid extraction, carnitine is measured enzymatically through its reaction with carnitine acetyltransferase coupled with acetyl coenzyme A and dithiobenzoate (DTNB).
