Which of the following compound is found in acid soluble pool during ananlysis of a living tissue?

Options

A. protein
B. Lipid
C. polysaccharide
D. monosaccharide

Answer

To solve the question "Which of the following compounds is found in the acid-soluble pool during the analysis of a living tissue?" we can follow these steps:

### Step 1: Understand the Analysis Process
When analyzing living tissue, the tissue is ground in a mortar and pestle and then treated with acetic acid. This process separates the components into two pools: the acid-soluble pool and the acid-insoluble pool.

**Hint:** Remember that the analysis involves grinding the tissue and adding acetic acid.

### Step 2: Identify the Two Pools
The two pools created during this analysis are:
- **Acid-soluble pool:** Contains smaller molecules and monomers.
- **Acid-insoluble pool:** Contains larger macromolecules.

**Hint:** Focus on what types of molecules are typically classified as soluble or insoluble in acid.

### Step 3: Determine the Composition of Each Pool
- **Acid-soluble pool:** This pool includes monomers such as monosaccharides (simple sugars), small amino acids, and other low molecular weight substances.
- **Acid-insoluble pool:** This pool includes larger molecules such as proteins, polysaccharides, and some lipids.

**Hint:** Think about the size and complexity of the molecules when categorizing them into pools.

### Step 4: Analyze the Options Given
The options provided are:
1. Protein
2. Lipid
3. Polysaccharide
4. Monosaccharide

From our understanding:
- Proteins, lipids, and polysaccharides are part of the acid-insoluble pool.
- Monosaccharides are part of the acid-soluble pool.

**Hint:** Recall which types of compounds are typically found in the acid-soluble pool.

### Step 5: Select the Correct Answer
Based on the analysis, the compound found in the acid-soluble pool during the analysis of living tissue is **monosaccharides**.

**Final Answer:** Monosaccharides (Option D) is the correct answer.
