Which sugar is classified as a disaccharide?

A sugar classified as a disaccharide is sucrose. Other important disaccharides include lactose and maltose.

Explanation:

• Disaccharides are sugars formed by the combination of two monosaccharides.
• They are linked by a glycosidic bond.

Examples of Disaccharide Sugars:

• Sucrose = glucose + fructose
• Lactose = glucose + galactose
• Maltose = glucose + glucose

Common Sources:

• Sucrose: table sugar, fruits
• Lactose: milk and dairy products
• Maltose: grains and starch digestion

Conclusion:
Sucrose is the most commonly recognized disaccharide sugar, along with lactose and maltose, all formed from two monosaccharide units.
