The Use of UV–Vis Absorption Spectroscopy for Studies of

Tryptophan (symbol Trp or W) is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3. It is encoded by the codon UGG. Weboften absorb light in the near-UV (150–400nm) or the visible(400–800nm)region. Absorption spectroscopy is usually performed with molecules dissolved in a transparent solvent, such as in aqueous buffers. The absorbance of a solute depends linearly on its concentration and therefore absorption spectroscopy is ideally suited for quantitative ... daily sports pw https://swrenovators.com
