Abstract
References

Introduction: Proteins are biomolecules made up of linear chains of amino acids that adopt complex three-dimensional structures and catalyze all cellular reactions in living beings. Objective: The present work aimed to identify the presence of proteins in 4 different milk samples. Methodology: This research was carried out through a qualitative approach with an experimental character, as it investigated the presence of proteins in different milk samples using the color change produced by specific chemical reactions as a reference. Result: All samples tested positive for the presence of proteins, with the color intensity varying in each sample. Discussion: The nutritional conditions of cattle can influence the characteristics of milk. Aspects such as feeding, type of forage, and nutritional management affect milk quality and production parameters. In addition, environmental and productive factors such as altitude, region, and management conditions can contribute to modifying its physicochemical properties. Conclusion: The purpose of the laboratory was fulfilled. The qualitative Biuret test made it easier to identify proteins in the milk samples. Furthermore, it was evidenced that the methodological execution and the study of the results were optimal. In conclusion, this assay is structured as a key preliminary test for the qualitative analysis of proteins.
