The snapshot below and shared PDF file has the summarized table of 1H, 13C and 15N chemical shifts of 20 common amino acids. I reformat the statistics from BMRB using the “average” values. I am lazy to dig webpages time by time when I need to check assignments of particular atoms. So making this table makes my life easier. The nomenclatures are BMRB format. For example Alanine HB is named MB as the 3 protons are constantly indistinguishable. The 1H, 13C and 15N are colored in black, red and blue, respectively.
If this table is useful for your NMR work, feel free to download it. A link of PDF format file is provided below.
