Figure 4. Section of the charge deconvoluted the ESI-FT-ICR-MS spectra (acquired in negative ion mode) of hydrazine-treated LTA of S. oralis Uo5∆cps (10).

Figure 4

The monoisotopic mass of 4959.69 Da corresponds to 10 with n = 2 (structure shown in Fig. 5A), the assigned higher masses to respective molecules with longer chains (6217.123 Da (n = 3); 7474.559 Da (n = 4); 8732.011 Da (n = 5)).
