WebDec 15, 2024 · Abstract. Proteins primarily absorb UV light due to the presence of tryptophan, tyrosine, and phenylalanine residues, with absorbance maxima at 280, 275, and 258 nm, respectively. We now demonstrate that a simple value obtained by relating the absorbance at all three wavelengths, [A280/A275 + A280/A258], is a generally useful, … WebThe peak at lower wavelengths is caused by absorbance of peptide and carboxylic acid moieties in the compounds. On a molar basis tryptophan absorbs more light at 280nm …
