Phenylalanine uv spectrum
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. Web4. máj 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 …
