Biuret test
The biuret test is a special test that helps us check if a substance has proteins in it. You know that proteins are very important for our bodies, right? They are the building blocks of our muscles, organs, and many other parts of us. So, this test is like detectives that check if a certain substance contains proteins or not.
Now, let me explain how this test works. Imagine you have a glass of juice that you want to test if it has proteins. First, you need to add a special chemical called the biuret reagent to the juice. This chemical will react with the proteins and change color if they are present.
If the juice does have proteins, the biuret reagent will turn from a blue liquid to violet-blue or purple. The darker the color, the more proteins are in the juice. If the juice does not have proteins, the color will stay blue.
So, that's basically how the biuret test works. Do you understand, little one?
