Chrysolaminarin is chemically

Options

A. `beta` 1-4 glucan
B. `beta` 1-6glucan
C. `alpha` 1-3 glucan
D. `beta` 1-3 glucan

Answer

**Step-by-Step Solution:**

1. **Understanding Chrysolaminarin**: Chrysolaminarin is a storage polysaccharide found in chrysophytes, which are a group of unicellular eukaryotic organisms.

2. **Chemical Composition**: Chrysolaminarin is primarily composed of glucose units. The specific types of glycosidic bonds that link these glucose units together determine its classification.

3. **Identifying the Glycosidic Bonds**: The options provided in the question include:
- Beta 1, 4-glucan
- Beta 1, 6-glucan
- Alpha 1, 3-glucan
- Beta 1, 3-glucan

4. **Correct Identification**: From the information provided, chrysolaminarin is identified as a water-soluble polysaccharide that contains:
- Beta 1, 3-glucan
- Beta 1, 6-glucan

5. **Conclusion**: Therefore, the correct answers for the chemical composition of chrysolaminarin are **Beta 1, 3-glucan** and **Beta 1, 6-glucan**.
