Question

The amino acid obtained from cheese is

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

- Tyrosine is a non-essential aromatic amino acid that plays a role in neurotransmitter production (dopamine, epinephrine).
- It is a precursor for melanin (skin pigment) and thyroid hormones.
- It is commonly found in cheese, turkey, and dairy products.

Answer 1

The Correct Option is A

Step 1: Identifying the Amino Acid from Cheese 
- The amino acid obtained from cheese is Tyrosine. 
- Tyrosine has a benzene ring with a hydroxyl (-OH) group, which is a characteristic feature of this amino acid. 
- It is classified as a non-essential aromatic amino acid. 

Step 2: Analyzing the Given Options 
- Option (1): Structure matches L-Tyrosine because it contains a phenol (-OH) functional group attached to a benzene ring. 
- Option (2): The structure corresponds to Phenylalanine, which lacks the hydroxyl (-OH) group. 
- Option (3): The structure corresponds to Serine, which has a hydroxyl (-OH) group but no benzene ring. 
- Option (4): The structure corresponds to Alanine, which contains only a methyl (-CH3) side chain. 

Step 3: Verifying the Answer 
- Since Tyrosine is the amino acid found in cheese, Option (1) is correct.
