[What is Huperzine A]

Huperzia is a type of moss that grows in China. It is related to club mosses (the Lycopodiaceae family) and is known to some botanists as Lycopodium serratum . The whole prepared moss was used traditionally. Modern herbal preparations use only the isolated alkaloid known as huperzine A. Huperzine A is an alkaloid found in huperzia that has been reported to prevent the breakdown of acetylcholine, an important substance needed by the nervous system to transmit information from cell to cell. Animal research has suggested that huperzine A’s ability to preserve acetylcholine may be greater than that of some prescription drugs. Loss of acetylcholine function is a primary feature of several disorders of brain function, including Alzheimer’s disease . Huperzine A may also have a protective effect on brain tissue, further increasing its theoretical potential for helping reduce symptoms of some brain disorders.

[Function] Used in alternative medicine, huperzine A has been found to act as a cholinesterase inhibitor, a type of medicine used to prevent the breakdown of acetylcholine (a chemical essential to learning and memory).

Not only used as a treatment for Alzheimer’s disease, huperzine A is also said to enhance learning and memory and to protect against age-related cognitive decline.

In addition, huperzine A is sometimes used to boost energy, increase alertness, and aid in the treatment of myasthenia gravis (an autoimmune disorder that affects the muscles).

ABOUT THE VIRTUAL LAB SIMULATION

The Blood Sugar Lab explores how carbohydrates are broken down by the digestive system and taken up into the bloodstream.

SUMMARIZED LEARNING OUTCOMES

- Explore the molecular structure of sugars and polysaccharides.
- Understand digestion and appreciate the complexity of the human body.
- Experiment with different foods and measure their impact on the blood sugar level.

DETAILED LAB DESCRIPTION

Carbohydrates – the energy for your body

A scientific paper states that carbohydrate loading can improve the performance of endurance cyclists. Your goal is to learn how carbohydrates are digested and taken up by the body to be used as energy source.

Study the molecular structures of carbohydrates

Use the in-lab molecule visualizer to study the chemical structure of sugars. Learn the basics about molecule structures and chemical formulas.

Learn how food is mechanically and enzymatically broken down

You are encouraged to perform a real experiment and sense how the amylase breaks down starch. A 3D animation will visualize the molecular process of carbohydrate digestion.

Measure the effect of different foods on the blood glucose level

Depending on the composition of food the effect on the blood glucose level is very different. You can choose different food items and measure the increase of the blood glucose level of a virtual test subject.
