The process of 'translation' in protein synthesis involves formation of a peptide bond between two amino acids that are attached to two distinct transfer RNAs (tRNAs). For long, scientists have been ...

The presence of amino acids on the prebiotic Earth is widely accepted, either coming from endogenous chemical processes or being delivered by extraterrestrial material. On the other hand, plausibly ...

A team led by LMU chemist Oliver Trapp reports in Nature Communications. The formation of peptide bonds – the chemical bond between amino acids – in protein synthesis is one of the most important ...

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 ...

All proteins are built from the same 20 amino acids. One of these, cysteine, was assumed not to have been present at the origin of life. In a new study, scientists have recreated how cysteine was ...

The molecular machines that cells use to build proteins are backed by a billion years of evolution. In that time, these machines—ribosomes—have become exceptionally good at forging amide bonds between ...

It’s expedition time, and peptideguide.com is here to lead you through the world of amino acids. This website is intended as an introduction to the field of peptide chemistry; as such, readers won’t ...
