Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

The predicted results almost were same as that of the actual result should be.

F. How might you use the Biuret reagent test in a practical real-life situation?

In real life situations the biuret test can be used for the detection of the protein content in the food. It can be

also used to detect the amount of the proteins excreted in the urine samples and also the stool.

G. What do you feel you have learned in doing this exercise?
