原始语种摘要: Abstract(#br)It is well established that homocysteine thiolactone (HTL) is associated with some health disorders, including cardiovascular diseases. HTL is a by-product of sulfur metabolic cycle. So far, its presence has been confirmed in human plasma and urine. It has been also shown that a vast majority of HTL is removed from human body through kidney. Thus, the aim of the current investigations has been the identification, separation and quantification of HTL in urine samples. For the first time a cheap, reliable and robust GC–MS method was developed for the determination of HTL in human urine in the form of its volatile isobutyl chloroformate derivative. Separation of the analyte and internal standard (homoserine lactone (HSL)) was achieved in 15 min followed by mass spectrometry...
