Newfound molecule has branched structure akin to amino acids’
A cold cloud of gas and dust near the center of the galaxy may create the molecular ingredients for life.
By searching the cloud called Sagittarius B2, researchers found the first branched organic chemical discovered in interstellar space: isopropyl cyanide. Its branched structure resembles that of many amino acids, fundamental components of life on Earth that link together to form proteins. The discovery, reported in the Sept. 26 Science, hints that compounds essential to life may arise in the mass of molecules between the stars before making their way to Earth and other planets.
