Abstract
Ämnesord
Stäng
- A close analogy exists between the mass spectrometric fragmentation of fully methylated aldopentopyranoses and trimethylsilyl derivatives of partially methylated aldopentopyranoses. Hence, mass spectrometry of the trimethylsilyl derivatives permits a simple determination of the number and position of methoxyl groups in partially methylated aldopentoses. Reference substances are not necessary for identification. The method is useful in studies of the structure of polysaccharides.
