Which disaccharide is commonly known as table sugar?

• A. Fructose
• B. Lactose
• C. Maltose
• D. Sucrose

Answer: (D)

The disaccharide that is commonly known as table sugar is sucrose. Sucrose is a carbohydrate composed of two monosaccharides: glucose and fructose. It is widely used as a sweetener in various food products and is abundant in sugar cane and sugar beets, which are the primary sources for commercial sugar. The term "table sugar" refers specifically to sucrose due to its widespread use in households and cuisine. In contrast, fructose is a monosaccharide found naturally in fruits; lactose is a disaccharide made up of glucose and galactose, primarily found in milk; and maltose consists of two glucose units and is found in malted foods and beverages. Each of these sugars has distinct sources and properties, but none are referred to as table sugar.
