Which of the following is an example of a typical homopolysaccharide?

Options

A. Lignin
B. Suberin
C. lnulin
D. Starch

Answer

To determine which of the following options is an example of a typical homopolysaccharide, we need to understand what a homopolysaccharide is.

### Step-by-Step Solution:

1. **Definition of Homopolysaccharide**: A homopolysaccharide is a type of polysaccharide that is composed of only one type of monosaccharide unit repeated multiple times. This means that all the monomers (the building blocks) are the same.

2. **Analyzing the Options**: We have four options to consider:
- A) Lignin
- B) Sobering
- C) Inulin
- D) Starch

3. **Identifying the Monosaccharide Composition**:
- **Lignin**: This is not a polysaccharide; it is a complex organic polymer that provides structural support in plants.
- **Soberin**: This is a type of waxy substance and not a polysaccharide.
- **Inulin**: This is a fructan, meaning it is made up of fructose units, but it is not a homopolysaccharide as it consists of different types of monosaccharides.
- **Starch**: This is a well-known homopolysaccharide made entirely of glucose units. It exists in two forms: amylose (linear) and amylopectin (branched), both of which are composed solely of glucose monomers.

4. **Conclusion**: Since starch is made up entirely of the same type of monosaccharide (glucose), it qualifies as a homopolysaccharide.

### Final Answer:
The answer to the question is **D) Starch**.
