Learn More About This Simulation
This short, targeted simulation is adapted from the full-length “Introduction to Food Macromolecules” simulation.
Discover the simple carbohydrates in your food! In this simulation, you will be introduced to the chemical structures of simple carbohydrates and the importance of simple carbohydrates within our diets. Begin by examining their structure and then learn how to test for the presence of simple sugars in food samples using Benedict's test.
Jump into the food sample
Begin by jumping inside a bottle of syrup to initiate an animation that explains the chemical building blocks that make up simple sugars. Identify the difference between aldose and ketose sugars. Learn about the linear and ring forms of monosaccharides, such as glucose and fructose, and find out how the linear form can change into ring form and vice versa. Discover how a glycosidic bond can form between two monosaccharides to make a disaccharide, such as lactose and sucrose. Finally, return to the lab to perform an experiment which will test for the presence of these simple sugars.
Use Benedict's test
You will assay food samples using Benedict’s test for simple carbohydrates. A range of food samples have been prepared and their respective solution placed in a test tube. Perform the test for each food sample and observe the color change over time. Identify the positive and negative result for the test. Then use what you have learnt to determine which food samples contain simple carbohydrates. Does your friend's salad contain simple carbohydrates?
Review your knowledge
Put your knowledge of simple carbohydrates to the test in quizzes throughout the simulation. Can you spot the differences and similarities between a variety of simple carbohydrates?

A Labster virtual lab is an interactive, multimedia assignment that students access right from their computers. Many Labster virtual labs prepare students for success in college by introducing foundational knowledge using multimedia visualizations that make it easier to understand complex concepts. Other Labster virtual labs prepare learners for careers in STEM labs by giving them realistic practice on lab techniques and procedures.
Labster’s virtual lab simulations are created by scientists and designed to maximize engagement and interactivity. Unlike watching a video or reading a textbook, Labster virtual labs are interactive. To make progress, students must think critically and solve a real-world problem. We believe that learning by doing makes STEM stick.
Yes, Labster is compatible with all major LMS (Learning Management Systems) including Blackboard, Canvas, D2L, Moodle, and many others. Students can access Labster like any other assignment. If your institution does not choose an LMS integration, students will log into Labster’s Course Manager once they have an account created. Your institution will decide which is the best access method.
Labster is available for purchase by instructors, faculty, and administrators at education institutions. Purchasing our starter package, Labster Explorer, can be done using a credit card if you are located in the USA, Canada, or Mexico. If you are outside of North America or are choosing a higher plan, please speak with a Labster sales representative. Compare plans.
Labster supports a wide range of STEM courses at the high school, college, and university level across fields in biology, chemistry, physics, and health sciences. You can identify topics for your courses by searching our Content Catalog.
