Chemical Shift Delta

The plotted chemical shift differences are to be used in conjunction with the chemical shift index plots provided for this entry. They have been calculated using the observed chemical shifts reported in the entry and the standard chemical shifts reported by Wishart and coworkers (see http://www.bmrb.wisc.edu/ref_info/csishift.txt).

Note that for cysteine, the standard chemical shift values for cysteine (ox) are used.
