Natural-abundance 15N NMR spectroscopy on dodecylguanidine reveals solvent and protonation effects that model those that could occur for the arginine side chain in proteins. Our results demonstrate ...

A team of scientists from France and Austria has discovered a new abiotic pathway for the formation of peptide chains from amino acids - a key chemical step in the origin of life. The current study ...

A team of scientists has discovered a new abiotic pathway for the formation of peptide chains from amino acids -- a key chemical step in the origin of life. The current study provides strong evidence ...

The sequence of the N-terminal ten amino acids of the unblocked light chains derived from the low molecular weight immunoglobulin of a dipnoid fish, the African lungfish (Protopterus aethiopicus), has ...

Earlier efforts to attach amino acids to RNA had relied on highly reactive compounds that quickly degraded in water and ...
