Pyrolysis of saccharides compared to ion fragments formation

Typical mass spectra fragments from saccharides are likely to have the following structures  

These fragments have good resemblance with compounds detected in pyrolysis of sugars (see Sections 7.1 and 7.2) such as  

Numerous structures can be proposed for the ion with m/z =97, which also have correspondents in the pyrolysates
