Maltose facts for kids
Maltose is a type of sugar that is also known as malt sugar. It's a disaccharide, which means it's made from two simpler sugar units joined together. Think of it like two building blocks of sugar connected!
Specifically, maltose is formed when two glucose molecules link up. Glucose is a very common and important sugar that our bodies use for energy. Maltose is found naturally in many places, especially in germinating seeds. For example, when barley seeds start to sprout, they break down their stored starch into maltose to use as food for the growing plant.

What is Maltose?
Maltose is a carbohydrate, which is a type of nutrient that gives us energy. It belongs to a group of sugars called disaccharides. The word "di" means two, so a disaccharide is a sugar made of two smaller sugar units. In the case of maltose, these two units are both glucose molecules.
These two glucose molecules are connected in a special way. They join at specific points called carbon atoms, creating a strong bond. This bond can be broken down by our bodies to release the glucose, which then provides energy.
Where Does Maltose Come From?
Maltose is found in many natural places. It's especially common in plants that are breaking down their stored energy.
In Seeds and Grains
When seeds like barley, wheat, or corn start to sprout, they need energy to grow. They store energy as starch. To use this starch, the seeds produce special chemicals called enzymes, like amylase. Amylase breaks down the large starch molecules into smaller maltose molecules. This maltose then provides the energy the young plant needs.
In Food and Drinks
Because of this natural process, maltose is found in many foods made from grains. It's a key ingredient in malted milk, beer, and some breakfast cereals. It's also used as a sweetener in candies and baked goods. When you eat starchy foods like bread or potatoes, your body's enzymes also break down the starch into maltose during digestion.
How is Maltose Used?
Maltose is important for both plants and humans.
For Plants
For a sprouting seed, maltose is like a quick energy snack. It's easily moved around the plant to fuel growth until the plant can make its own food through photosynthesis.
For Humans
When we eat foods containing maltose, our bodies break it down even further. An enzyme called maltase splits maltose into its two glucose units. These glucose units are then absorbed into our bloodstream and used by our cells for energy. This energy powers everything we do, from thinking to running.
Maltose is also used in the food industry. It gives a slightly less sweet taste than regular sugar (sucrose) and can help foods stay fresh longer. It's also used in brewing beer, where yeast ferments the maltose to produce alcohol.
