Typically patients diet immediately prior to surgery, which causes low intake of the vitamin and the water soluble nature of vitamin B1 which means it quickly leaves your tissues
In addition to the annotated MS2 spectra, Byos also displays the associated XICs for the modified peptide with a red dot indicating the retention time of the selected scan for MS2 display, and pink dots indicating the retention time from all scans that have an exact match in terms of sequence and modification type and location
Pernicious Anemia: Parenteral vitamin B12 is the recommended treatment and will be required for the remainder of the patient's life
