The first practical method for the determination of hexosamines was worked out by Elson and Morgan (1). Since that time many modifications have been introduced in an attempt to increase the sensitivity and reproducibility of the technique (2) and to decrease the effect of interfering substances (3)

## Abstract We present a method employing top‐down Fourier transform mass spectrometry (FTMS) for the rapid profiling of amino acid side‐chain reactivity. The reactivity of side‐chain groups can be used to infer residue‐specific solvent accessibility and can also be used in the same way as H/D exch
