Which of the following sugars is a monosaccharide and also an Aldo?Group of answer choicesGlucosesucroseFructoselactose

The sugar that is a monosaccharide and also an Aldo is Glucose.

Here's why:

1. Monosaccharides are the simplest form of carbohydrates and cannot be broken down into simpler sugars. They are the building blocks of disaccharides like sucrose and lactose, and polysaccharides like starch and cellulose.

2. Aldoses are a type of monosaccharide that contains an aldehyde group.

3. Glucose is a monosaccharide and it contains an aldehyde group, so it is also an Aldo.

4. Sucrose and lactose are disaccharides, not monosaccharides.

5. Fructose is a monosaccharide, but it is a ketose, not an Aldo, because it contains a ketone group.
