Abstract
The use of 13C
N.M.R. for the identification of the site of cross- linking of amino acids by
formaldehyde has been evaluated by use of model compounds, such as 2,4-dimethylphenol
for tyrosine. The 13C chemical shifts of the formaldehyde-derived
methylene carbons occur within the range 50-60 p.p.m.
downfield from Me4Si. Estimated shifts in lysine-lysine and
tyrosine-glutamine cross-linked systems fall just outside this region. The 13C
spectra of a number of related phenols, amines and protected amino acids are
also reported.
