Glucose cannot be classified as?

Options

A. Hexose
B. Carbohydrate
C. Aldose
D. Oligo saccharide

Answer

To determine what glucose cannot be classified as, we will analyze its characteristics and classifications step by step.

### Step 1: Identify the classification of glucose
Glucose is a type of sugar known as a monosaccharide. Monosaccharides are the simplest form of carbohydrates and consist of a single sugar unit.

**Hint:** Remember that monosaccharides are the basic building blocks of carbohydrates.

### Step 2: Understand the structure of glucose
Glucose has a molecular formula of C6H12O6, indicating that it contains six carbon atoms. It typically exists in a ring form in solution.

**Hint:** Focus on the number of carbon atoms in glucose to help classify it.

### Step 3: Differentiate between monosaccharides and oligosaccharides
Oligosaccharides are carbohydrates that consist of 2 to 10 monosaccharide units linked together. Since glucose is a single unit, it does not fit this classification.

**Hint:** Recall that oligosaccharides are made up of multiple monosaccharides.

### Step 4: Consider other classifications
- Glucose can be classified as a hexose because it contains six carbon atoms.
- Glucose can also be classified as an aldose because it contains an aldehyde group.

**Hint:** Think about the functional groups and the number of carbon atoms when considering other classifications.

### Conclusion
Based on the analysis, glucose cannot be classified as an oligosaccharide because it is a single monosaccharide unit, while oligosaccharides consist of multiple units.

**Final Answer:** Glucose cannot be classified as an oligosaccharide.
