A key precursor in the synthesis of aromatic amino acids (tryptophan,tyrosine and phenylalanine)is ________.

Question

Quizplus · Accepted Answer

The key precursor in the synthesis of aromatic amino acids is chorismate. It is an intermediate in the shikimate pathway, which is responsible for the synthesis of aromatic compounds in plants, bacteria, and fungi. Chorismate is converted into prephenate, which is then converted into the aromatic amino acids. Therefore, prephenate is not the correct answer as it is an intermediate in the synthesis of the amino acids. 4-hydroxyphenylpyruvate and indole are intermediates in the synthesis of tyrosine and tryptophan, respectively, but not in the synthesis of all the aromatic amino acids.
