WebNational Center for Biotechnology Information WebMay 4, 2016 · Introduction. The UV absorption of proteins in the range 180 to 230 nm is due almost entirely to π → π ∗ transitions in the peptide bonds. Absorption in the range of 230–300 nm is dominated by the aromatic side-chains of tryptophan (Trp), tyrosine (Tyr), and phenylalanine (Phe) residues, and there is weak contribution by disulphide bonds near …
