Fig. 3: Confirmation of the structural assignment of feature A and B with synthetic reference standards.
From: Identification of Δ-1-pyrroline-5-carboxylate derived biomarkers for hyperprolinemia type II
Comparison of the experimental IR spectra of a feature A (black trace) and reference standard 4cis (blue line) with theoretical IR spectrum of 4cis (orange trace), b feature A (black trace) and reference standard 4trans (blue line) with theoretical IR spectrum of 4trans (orange trace). Molecular structures corresponding to the protonated reference standards are inlayed in each panel.
