Aromatic amino acid

These aromatic amino acids are the precursors of many secondary metabolites, all essential to a plant's biological functions, such as the hormones salicylate and auxin.

Herbicides and antibiotics work by inhibiting these enzymes involved in the biosynthesis of aromatic amino acids, thereby rendering them toxic to plants.

In addition to destroying greens, Glyphosate can easily affect the maintenance of the gut microbiota in host organisms by specifically inhibiting the 5-enolpyruvylshikimate-3-phosphate synthase which prevents the biosynthesis of essential aromatic amino acids.

[9] Excessive intake of aromatic amino acids far beyond levels obtained through normal protein consumption might lead to hypertension,[10] something which could go un-noticed for a long time in healthy individuals.
