Abstract

^13^C chemical shifts and coupling constants of phosphoserine in aqueous solutions were studied as a function of pH values. Carboxyl and α‐amino titration shifts agree with those observed in amino acids. The analysis of the coupling constants indicates that for rotation about the (C)CO(P) axis the trans conformer predominates for all pH values. The fractional population of the gauche conformer reaches a maximum at pH=8.
