To confirm Bennu’s amino acids were not contaminated by Earth, scientists analyzed their chirality (handedness). Life on Earth exclusively uses left-handed amino acids, while non-biological processes ...

More than half of all modern medicines are chiral. Since biomolecules such as amino acids, sugars and proteins in our body all have the same handedness, active pharmaceutical ingredients must also ...

Many biopolymers such as DNA form helices, which are inherently chiral structures, while compounds such as amino acids form complex 3D shapes that also can have left and right forms. Researchers now ...

For example, Dieter Enders and Wolfgang Bettray nicely detail the applications of Enders' chiral auxiliary (S)-1-amino-2-methoxymethylpyrrolidine (SAMP) to the chemical syntheses of several chiral ...

The discovery challenges the long-held belief that life’s building blocks—specifically, amino acids and sugars—were strictly ...

Research suggests that calcium may have played a key role in guiding the development of a specific molecular handedness in ...

In the past several decades, significant progress has been made in controlling molecular chirality, as evidenced by the several Nobel Prizes in chemistry awarded in this area, particularly for ...

such as sugars and amino acids, come in two forms. These forms – called enantiomers – are mirror images of one another, just like our left and right hands are. The phenomenon is called chirality, and ...

This process could have amplified small imbalances in chirality, ultimately leading ... in terms of biomolecules like nucleic acids and amino acids," ELSI's Specially Appointed Associate Professor ...
