Figure 8. Ac-YHD PE crosslink forms when PE is incubated with Ac-YHNEF.

Figure 8.

a) HPLC profile of Ac-YHNEF incubated at 60 °C with a five-fold molar excess of PE at pH 6.7 for 3 days. Detection at 280nm b) MS/MS spectrum of the Ac-YHD x PE peak isolated by HPLC. * = loss of PE, MI = molecular ion.
