Large molecules ar called because of large. In this picture, we look At how to conduct out the chemic tests for amylum, protein and lipids. Benedict's test is victimised to detect sugars. Many proteins also stop sulfur. The building blocks of proteins ar the amino acids.

How are carbohydrates detected in chemical and physical tests?

They can be detected using chemical and physical tests. There are different tests which can be used to detect carbohydrates, proteins and lipids. Starch is detected using iodine solution. This turns blue-black in the presence of starch. Reducing sugars are detected using Benedict’s solution.

Can you take a quiz on atoms, elements, and molecules?

This quiz can be used as a pre-test for a unit on atoms, molecules, elements, and compounds. The quiz will, along with a post-test, serve as a method to determine how much the students have learned after the science unit has been taught.
