Peptides, one of the fundamental building blocks of life, can be formed from the primitive precursors of amino acids under conditions similar to those expected on the primordial Earth, finds a new UCL study. The findings, published in Nature, could be a missing piece of the puzzle of how life first formed. “This is the first time that peptides have been convincingly shown to form without using amino acids in water, using relatively gentle conditions likely to be available on the primitive Earth,” said co-author Dr Saidul Islam (UCL Chemistry). Learn More
