Structural analysis of peptides with nuclear magnetic resonance (NMR) spectroscopy generally relies on knowledge of the primary sequence to enable assignment of the resonances prior to determination of the three-dimensional structure. Resonance assignment without knowledge of the sequence is complicated by redundancy in amino acid type. making complete de novo sequencing using NMR spe... https://www.roneverhart.com/Martin-000-15SM-15-Series-12-Fret-Acoustic-Guitar-p19001/
