Step 1:
I'll solve this step by step with clear explanations:

Step 2:
: Identify the structure of Asn (Asparagine)

- Asparagine is an amino acid with a specific molecular structure - Its full chemical name is 2 -amino- 3 -carbamoylpropanoic acid

Step 3:
: Analyze the functional groups in Asparagine

- Asparagine contains two key functional groups: 1) Amide group (in the side chain) 2) Carboxylic acid group (in the backbone) 3) Primary amine group (in the backbone)

Step 4:
: Verify each functional group option

1) Amide ✓ CORRECT - The side chain contains a clear amide (-CONH₂) group 2) Primary amine ✓ CORRECT - The amino acid backbone contains an -NH₂ group 3) Carboxylate ✗ INCORRECT - Contains a carboxylic acid group, not a carboxylate (which is the deprotonated form) 4) Aldehyde ✗ INCORRECT - No aldehyde group is present in Asparagine

Final Answer

1) Amide 2) Primary amine
