The Nobel Prize in Chemistry 1988[1]
Photosynthesis - the most important chemical reaction on earth. In the green leaves of plants solar light is converted to chemical energy, which is used as nutrition not only by the green plants themselves but also for example: by cows who eat green grass, by ourselves who eat the meat of the cow and drink its milk, and so on through the nutritional chain.
