Sulfur molecules from space may have seeded early life on Earth

Necessary vitamins for the primary residing organisms on Earth could have come from space, in line with new analysis from the College of Hawaiʻi at Mānoa.

Division of Chemistry scientists found that sure sulfur-containing organic molecules, referred to as alkylsulfonic acids, can kind naturally in space with out the presence of life and have been delivered to Earth by comets and asteroids.

Sulfur-containing natural molecules are important for all times on Earth as they’re essential for a lot of biological processes, reminiscent of protein structure and performance, enzyme activity, and mobile respiration to include sulfur.

These natural molecules have been created in laboratory simulations that mimic the situations of interstellar ices present in space. The examine additionally discusses how this discovery might assist scientists detect these molecules on comets and asteroids, such because the carbonaceous asteroid Ryugu, offering insights into the chemical processes which may contribute to the origins of life on Earth.

The work is published within the journal Nature Communications.

“Our discovery highlights the creativity and persistence of scientists in fixing long-standing mysteries about life’s beginnings, inspiring curiosity and curiosity in scientific exploration and analysis,” mentioned UH Mānoa Professor Ralf I. Kaiser who is likely one of the examine’s authors. “Understanding this course of can ignite imaginations about our place within the universe and the origins of life itself.”

“Life as we all know it requires sulfur, and historical water-soluble alkylsulfonic acids are a believable method to incorporate sulfur into early organisms,” added Mason McAnally, a UH Mānoa chemistry Ph.D. scholar and lead creator.
