Answer
Tyrosine
Explanation
Solution
Tyrosine is not an essential amino acid. While it is an important amino acid in the body, it is considered non-essential because it can be synthesized from the essential amino acid phenylalanine. The essential amino acids are those that cannot be synthesized by the body and must be obtained from the diet.
So, the correct option is (D): Tyrosine.
