Kagan and Kenso Soai "for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis."
Kagan, who is 95 years old and was born in France, is affiliated with France’s Université Paris-Sud, and Soai, who is 76 years old and was born in Japan, is based at the Tokyo University of Science.
The scientists share the Nobel Prize for answering longstanding questions in chemistry about life's origins.
Specifically, the duo solved an age-old mystery that has long puzzled chemists: some molecules, like amino acids, exist as two variants that are mirror images of one another, but just one of the variants out of the two is found in living organisms.
The two answered questions about why life chooses one variant over another.
The Royal Swedish Academy of Sciences announced the winner in Stockholm.
In chemistry, life's chemistry is what scientists call homochiral, after the Greek words for "same" and "hand."
The Nobel Committee said the chemistry prize recognizes discoveries that have enabled chemists to drive chemical reactions that lead to homochirality.
"Henri Kagan and Kenso Soai have provided a solution to a chemical mystery that is over a century old: how homochirality can emerge spontaneously," Heiner Linke, chair of the Nobel Committee for Chemistry, said in a news release. "The chemical reactions they have developed are spectacular."
The duo's discoveries, the news release said, "have been decisive for chemists who design reactions for the manufacture of pharmaceuticals."
Last year, Susumu Kitagawa, Richard Robson and Omar Yaghi won the Nobel Prize in chemistry for the development of new molecular structures that can trap vast quantities of gas inside. Their discoveries can help tackle some of the world's most pressing problems, like climate change.
