WebSep 15, 2024 · The biuret test is a chemical assay used to determine the presence of peptide bonds in a molecule. The assay is based on the principle that the copper (II) ion, Cu2+, will form a violet complex with peptide bonds in a solution. The intensity of the violet color is used to determine the presence of peptide bonds. WebMar 18, 2024 · A biuret matrix species is defined to cover the effect of solidification at 220 °C. Ammelide decomposition is modeled as sublimation while further high molecular by-products are not included in the model. Further, recent investigations have shown that the current kinetic model lacks a reproduction of mass transfer effects at the sample surface ...
