Which of the following sugars is a disaccharide?Group of answer choicesfructosesucrosegalactoseglucose

Identification of Disaccharides

To determine which of the options is a disaccharide, we need to know the definitions of the listed sugars.

1. Fructose: This is a monosaccharide, a simple sugar that cannot be hydrolyzed into simpler sugars.
2. Sucrose: This is a disaccharide composed of glucose and fructose. It is commonly known as table sugar.
3. Galactose: This is also a monosaccharide.
4. Glucose: This is another monosaccharide, a simple sugar.

Summary and Final Answer

Among the given options, sucrose is the only sugar that is classified as a disaccharide. It consists of two monosaccharides (glucose and fructose) linked together. Therefore, the correct answer is:

Sucrose.
