Draw the Structural formula of the compound :
2-Amino-3-hydroxy-4-oxo-pentanoic acid

Answer

To draw the structural formula of the compound 2-Amino-3-hydroxy-4-oxo-pentanoic acid, we will follow these steps:

### Step 1: Identify the main chain
The name "pentanoic acid" indicates that the main carbon chain consists of five carbon atoms, and it has a carboxylic acid functional group (-COOH) at one end.

**Hint:** The prefix "pent-" indicates five carbon atoms in the main chain.

### Step 2: Draw the carbon chain
Start by drawing a straight chain of five carbon atoms. The carboxylic acid group will be at the first carbon:

```
C1 - C2 - C3 - C4 - C5
```

**Hint:** Remember that the carboxylic acid group is always at the first carbon when no number is specified.

### Step 3: Add the carboxylic acid group
At the first carbon (C1), add the carboxylic acid group (-COOH):

```
O
||
C1 - C2 - C3 - C4 - C5
|
OH
```

**Hint:** The carboxylic acid group is represented as -COOH, which includes a carbonyl (C=O) and a hydroxyl (OH) group.

### Step 4: Add the amino group
The name indicates that there is an amino group (-NH2) at the second carbon (C2). Replace one hydrogen atom on C2 with the amino group:

```
O
||
C1 - C2(NH2) - C3 - C4 - C5
|
OH
```

**Hint:** The amino group is represented as -NH2, which replaces one hydrogen atom on the carbon.

### Step 5: Add the hydroxy group
At the third carbon (C3), we need to add a hydroxy group (-OH). Replace one hydrogen atom on C3 with the hydroxy group:

```
O
||
C1 - C2(NH2) - C3(OH) - C4 - C5
|
OH
```

**Hint:** The hydroxy group is represented as -OH, which is added to the carbon chain.

### Step 6: Add the oxo group
At the fourth carbon (C4), we need to add an oxo group (C=O). This means we will have a double bond to oxygen:

```
O
||
C1 - C2(NH2) - C3(OH) - C4(=O) - C5
|
OH
```

**Hint:** The oxo group is represented as a carbonyl (C=O) and is added to the specified carbon.

### Final Structure
Putting it all together, the complete structural formula for 2-Amino-3-hydroxy-4-oxo-pentanoic acid is:

```
O
||
HOOC - C2(NH2) - C3(OH) - C4(=O) - C5
```

### Summary
The structural formula of 2-Amino-3-hydroxy-4-oxo-pentanoic acid consists of a five-carbon chain with a carboxylic acid at one end, an amino group on the second carbon, a hydroxy group on the third carbon, and an oxo group on the fourth carbon.
