... enough for the green rust to react with in order to produce the amino acid alanine and the alpha hydroxy acid lactate. These latter acids are byproducts of amino acid reactions, however some scientists theorise they too could bond to form...
... reactions, Krishnamurthy and team found that in addition to CO2, the chemistry also produced these much needed amino acids. The researchers think that as biological molecules like enzymes became available, they could have led to the...
... to explain the origin of life. The simplest sugar glycolaldehyde (CH2OHCHO), for example, is involved in the formation of amino acids and can react with another sugar, propenal, to produce ribose. Ribose is an important component of nucleotides, and...

... have been very interesting to know if comets agree. But it still should be feasible to at least find precursor molecules of amino acids if they are there. Our Kuiper belt comet 67P/C-G seems to be a fantastic object to study. We were very much...
