Tryptophan uv spectrum
WebMay 4, 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 near … WebTryptophan C11H12N2O2 CID 6305 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. …
