The herbicide glyphosate (Roundup®) kills plants by inhibiting an enzyme needed for the synthesis of phenylalanine. Deprived of phenylalanine, the plant cannot make the proteins it needs, and it gradually weakens and dies. Although a small amount of glyphosate is deadly to a plant, its human toxicity is quite low. a. Suggest why this powerful herbicide has little effect on humans. (b) Discuss the chemical properties of Glyphosate as an herbicide.
