What are the three disaccharides made from?

The three main disaccharides - sucrose, lactose, and maltose - are made from combinations of monosaccharides, which are simple sugars.

Composition of Each Disaccharide:

1. Sucrose:

• Made from glucose + fructose
• Found in table sugar, sugarcane, and fruits

1. Lactose:

• Made from glucose + galactose
• Present in milk and dairy products

1. Maltose:

• Made from glucose + glucose
• Formed during the digestion of starch

How They Are Formed:

• Disaccharides are formed through a condensation reaction (dehydration synthesis)
• A molecule of water (H₂O) is removed when two monosaccharides join via a glycosidic bond

Conclusion:
Disaccharides are made by combining two monosaccharides, with sucrose, lactose, and maltose being the most important examples.
