Ancient evidence suggests a new twist in how we all got here.

A machine-learning model from MIT researchers computationally breaks down how segments of amino acid chains determine a protein’s function, which could help researchers design and test new proteins ...

The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on ...

Amino acids are molecules fundamental to living organisms because they combine to build proteins, the workhorses of the cell. One metabolic pathway that produces amino acids involves transamination, a ...

The first amino acid, discovered in 1806, had a disarmingly ordinary source: asparagus juice. Hence the name asparagine. The next amino acids to be discovered had sources that were, if anything, even ...
