Table 3. Mean Amide ¹⁵N Chemical Shifts (ppm) for Serine/Threonine Resonances Across All Peptides as a Function of Side Chain and Post-Translational Modification^a.

	OH	OPO₃H^–	OPO₃^2–	Δδ^b
Ser	118.2	116.9	120.8	2.6
Thr	118.1	119.3	124.3	6.2

Full tabulated NMR data and statistical analysis are in the Supporting Information.

Δδ = δ (Ser/Thr(OPO₃^2–)) – δ (Ser/Thr(OH)).
