Answer / moumita ghosal
it is due to tryptophan and tyrosine.phenylalanine absorbs
at 260nm. but the former two has absorbance maxima at
280nm. absorbance is due to resonance phenomena of the
rings present in these amino acids.

Cystine (two cysteines joined in a disulfide bridge) also
absorb at 280nm along with the aforementioned tryptophan
and tyrosine.
