The CPS–PG linkage is susceptible to acetolysis. GC/MS analysis of CPS–PG following acetolysis. (A) Total ion chromatogram of the high MW fraction. (B) Selective ion monitoring of the high MW fraction at m/z 173 revealed no GlcNAc. (C) Total ion chromatogram of the low MW fraction. (D) Selective ion monitoring of the low MW fraction at m/z 173. kCounts, kilocounts.
