In this paper the two famous French chemists announced the first isolation of, and the naming of the substance Chlorofyll, the green substance essential for photosynthesis.

Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesise carbohydrates from CO2 and water. This process is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants, photosynthesis can be said to be the source of our life also.
