Glyphosate weed killer molecule. Computer model showing the molecular structure of a molecule of the herbicide glyphosate. Glyphosate is a widely used herbicide.

This weed killer is popular because it has very little effect on animals, as they do not make these amino acids in their bodies but obtain them from their diet. Atoms are represented as spheres and are colour-coded: carbon (black), hydrogen (white), nitrogen (blue), oxygen (red), and phosphorus (yellow) - with the bonds between them as rods
