The Royal Swedish Academy of Sciences honoured the duo for discovering non-linear effects and autocatalysis in asymmetric organic synthesis.

A Nobel Prize In Chemistry For Solving Nature’s One-Sided Secret
The 2026 Nobel Prize in Chemistry has gone to Henri B. Kagan and Kenso Soai. The French and Japanese chemists cracked a decades-old puzzle. Why does nature pick only one mirror-image form of certain molecules? Their answer matters hugely for drug development across the world.
The Royal Swedish Academy of Sciences praised the pair for their landmark discovery. “””For the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis,””” the Nobel jury said.
Why This Nobel Prize In Chemistry Matters To Medicine
Picture your two hands. They look alike, yet they’re mirror images, not identical twins. Amino acids behave the same way.
Every amino acid exists in two mirrored shapes. Only one shape ends up inside proteins found in human cells. Its mirrored partner almost never turns up in nature.
The Homochirality Puzzle Behind This Year’s Nobel Prize In Chemistry
Scientists call this one-sided pattern homochirality, the Academy explained. Kagan and Soai’s research explains how this imbalance forms at a molecular level. Their discovery could reshape how future medicines get designed and built.
