   Sammanfattning : Trimethylamine-n-oxide (TMAO) is a metabolite found in plasma/serum in humans. Elevated levels of TMAO have been associated with several types of heart disease. It’s therefore of interest to make a simple analytical method to analyse TMAO and other metabolites that are degraded to TMAO, including betaine. LÄS MER

3. 2. Determination of testosterone esters in serum by liquid chromatography – tandem mass spectrometry (LC-MS-MS)

   Kandidat-uppsats, Organisk Analytisk Kemi

   Författare :Erica Törnvall; [2010]
   Nyckelord :LC-MS-MS; MRM; testosterone; testosterone esters;

   Sammanfattning : Anabolic androgenic steroids are testosterone and its derivates. Testosterone is the most important naturally existing sex hormone for men and is used for its anabolic effects providing increased muscle mass. Testosterone is taken orally or by intramuscular injection in its ester form and are available illegally in different forms of esters. LÄS MER
