This laboratory experiment aimed to determine the presence of protein in various samples using Biuret solution. Biuret solution, containing copper ions, undergoes a color change when it reacts with peptide bonds in proteins. The color change from blue to violet indicates the presence of proteins in the sample. Different solutions, including albumin, gelatin, glucose, water, and an unknown solution, were tested for the presence of proteins. The initial and final colors were recorded, and the results were analyzed to determine protein presence.
Proteins play a crucial role in our bodies, serving as building blocks for various cellular functions. Detecting the presence of proteins in food or other substances is important for understanding their nutritional value. Biuret solution, containing copper ions, forms a complex with peptide bonds in proteins, leading to a color change from blue to violet. In this experiment, we utilized Biuret solution to test different solutions for the presence of proteins and recorded the color changes to draw conclusions about their protein content.

|5 - Unknown
The results of this experiment demonstrated the presence or absence of proteins in different solutions based on the color change observed after adding Biuret solution. The initial and final colors of each sample were recorded in Table 1.
This laboratory experiment successfully utilized Biuret solution to detect the presence of proteins in various solutions. The color changes observed in the test tubes indicated the presence or absence of proteins. The results were consistent with our hypotheses and the known properties of Biuret solution. This method can be valuable in nutritional and biochemical studies to determine the protein content of different substances.
Further experiments can explore the quantification of protein concentration in solutions using Biuret solution, providing more detailed information about protein content. Additionally, the application of other reagents, such as Benedict's reagent and iodine-potassium iodide, can be investigated for the detection of different biomolecules.
