Quizplus · Accepted Answer

Herbicides like Roundup that inhibit biosynthesis of "essential" amino acids are safe for animal exposure because animals do not have enzymes for Phe, Val, Leu, and Ile biosynthetic pathways.

Therefore, herbicides that target the biosynthesis of these amino acids in plants will not affect animals.
