Which of the following is called as Levulose ?

Options

A. Glucose
B. Fructose
C. Lactose
D. Maltose

Answer

To determine which of the following is called Levulose, we can follow these steps:

### Step 1: Understand the term "Levulose"
Levulose is another name for a specific type of sugar that has the ability to rotate plane-polarized light to the left. This property is known as "levorotation."

### Step 2: Analyze the options given
The options provided are:
- Glucose
- Fructose
- Lactose
- Maltose

### Step 3: Identify the sugar that is Levulose
- **Glucose**: This is a monosaccharide but does not rotate light to the left; it rotates it to the right.
- **Fructose**: This is also a monosaccharide and is known to rotate plane-polarized light to the left. It is commonly referred to as Levulose.
- **Lactose**: This is a disaccharide (composed of glucose and galactose) and does not have the properties of Levulose.
- **Maltose**: This is also a disaccharide (composed of two glucose units) and does not exhibit the properties of Levulose.

### Step 4: Conclusion
Based on the analysis, the sugar that is called Levulose is **Fructose**.

### Final Answer:
**Fructose** is called Levulose.
