Answer (1 of 2): Although by convention, textbooks only classify three amino acids (phenylalanine, tyrosine, and tryptophan) as aromatic, a fourth amino acid (histidine) is both aromatic and slightly basic. The binding of protein to the dye results in a change of color from brown to blue. In addition, this method also requires an extremely small sample volume since modern spectrophotometers use a sample retention system during the measurement. We have proposed that the experiments done under the 21% oxygen tension conditions more closely resemble those of an aging environment because of the higher concentration of reactive oxygen species compared to those under a 3% oxygen environment. Why Does Tyrosine and Tryptophan Have Effect in Protein Determination In contrast, oxidized derivatives of Trp (e.g., Kyn) appear to block the anabolic signals associated with the unoxidized amino acid counterparts, suggesting that with aging and the accompanying increase in oxidative stress, nutrient signals that normally promote osteoblastic proliferation and differentiation are converted into factors that inhibit these processes. Aromatic Amino Acid. These data would suggest that oxidation of some amino acids have additional harmful effects on stem cell function. Thus, conditions which affect structure (such as temperature, pH, ionic strength, or the presence of detergents) can affect the ability of aromatic residues to absorb light at 280 nm, and change the value of the proteins extinction coefficient. Age-related loss of bone mass and strength has been linked to increased ROS release from leaky mitochondria and their effects on bone cells (Manolagas, 2010). Tyrosine and tryptophan molecules absorb the UV light at 280 nm. Membranes were blocked with blocking buffer (cat#927-40000; Licor Biosciences).
