“[A]biotic synthesis of aromatic amino acids might be possible in the water–rock interface of Enceladus’s subsurface ocean,” the scientists explain. That’s only as far as Saturn. Maybe a ...

A novel protein cage system can control and visualize orientational changes in aromatic side chains upon ligand binding. By inducing coordinated molecular changes, this approach enables precise ...

There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. Amino acids are in an equilibrium between two acids with ...

NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission has detected amino acids in the largest asteroid sample ever collected in space, ...

Red Meat Amino Acids for Beginners ... The carcinogenic effects of red meat are associated with heterocyclic aromatic amines and polycyclic aromatic hydrocarbons, which are produced during ...
