Alcohol not metabolised is chagned into

Options

A. Butanol
B. Butyric acid
C. Acetic acid
D. Acetaldehyde

Answer

To solve the question "Alcohol not metabolised is changed into," we can follow these steps:

### Step 1: Understand the Metabolism of Alcohol
Alcohol, specifically ethanol, is primarily metabolized in the liver. The main metabolic pathway involves converting ethanol to acetaldehyde through an oxidative process.

**Hint:** Remember that the liver plays a crucial role in metabolizing substances, including alcohol.

### Step 2: Identify the Key Enzymes and Pathways
The main system responsible for the oxidation of ethanol is the microsomal ethanol-oxidizing system (MEOS). This system catalyzes the conversion of ethanol to acetaldehyde.

**Hint:** Look for the enzymes involved in the oxidation process of ethanol.

### Step 3: Recognize the Intermediate Product
After ethanol is converted to acetaldehyde, further metabolism occurs. Acetaldehyde can then be converted into acetate, which is a more stable compound.

**Hint:** Think about what happens to acetaldehyde after it is formed.

### Step 4: Analyze the Options Given
The options provided are butanol, butyric acid, acetic acid, and acetyl aldehyde. Since we know that ethanol is converted to acetaldehyde, we can eliminate options that are not directly related to this pathway.

**Hint:** Focus on the direct products of ethanol metabolism.

### Step 5: Determine the Correct Answer
Since the question specifically asks for what alcohol that is not metabolized is changed into, the correct answer is acetaldehyde. This is because acetaldehyde is the immediate product formed from the oxidation of ethanol before it is further metabolized into acetate.

**Final Answer:** Alcohol not metabolised is changed into acetaldehyde.

### Summary of Steps:
1. Understand the metabolism of alcohol.
2. Identify the key enzymes and pathways involved.
3. Recognize the intermediate product (acetaldehyde).
4. Analyze the options provided.
5. Determine the correct answer based on the metabolic pathway.
