Abstract

Solutes normally cleared by the kidneys accumulate and cause illness when the kidneys fail. Untargeted metabolomics provides an ideal mean to expand our knowledge of these "uremic" solutes.The current study employed the Q Exactive to profile solutes that accumulate in kidney failure patients maintained onhemodialysis. The discovery phase revealed 400 uremic components in negative ESI mode and 175 uremic components in positive ESI mode. Chemical identification using MS/MS scans from Q Exactive has revealed novel uremic solutes including N-glutamylhexenoic andN-glutamylheptenoic acid and is proceeding.
