UV–Vis spectroscopy of tyrosine side-groups in studies of protein ...

WebThe absorbance of ultraviolet light by tryptophan is greatest, that of tyrosine is less, and that of phenylalanine is least. If the tyrosine or tryptophan content of the protein is known, therefore, the concentration of the protein solution can be determined by measuring its absorbance between 280 and 290 nanometres. WebUV spectroscopic characterization of type I collagen The near UV absorption of type I collagen can be used to measure its tyrosine content and, therefore, the integrity of the nonhelical telopeptides. The far UV absorption of the protein can be used to determine its concentration and to monitor its thermal denaturation.

WebAmong biopolymers, proteins are unique in displaying useful intrinsic fluorescence. Lipids, membranes, and saccharides are essentially nonflu-orescent, and the intrinsic fluorescence of DNA is too weak to be useful. In proteins, the three aromatic amino acids— phenylalanine, tyrosine, and tryptophan—are all fluorescent.
