For proteins, the absorbance is related to the Tyrosine, Pheynylalanine, and Tryptophan rings. ... The Phenol ring of Phenylalanine actually absorbs weakly at 260 so the dominate UV-vis features of proteins are the tyrosyl and the indole which absorb at 280 nm. Conversely, the nucleobases absorb well at 260 nm.
