Much like our hands are non-superimposable images of themselves, many molecules are also chiral. Amino acids, the building blocks of protein, have chiral forms, that is, where one form is left ...

Amino acids, for example, can be either right- or left-handed mirror-images of each other. However, they are always left handed when produced by living organisms. This is important because chirality ...

All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying this observation is elusive. Recently, scientists uncovered new clues about the cosmic ...

In fact, this example is so ideal that chemists and molecular biologists dub chiral molecules as having either "left-handed" or "right-handed" chirality. Noted in the paper, sugars and amino acids -- ...

The α-helix is defined by having 3.6 amino acids in each turn such that each amino acid residue wraps itself around 100°, and 13 atoms in each ring. Chiral molecules ...

The laser pulses employed are unique in their extreme bandwidth in the deep-UV, continuously spanning wavelengths of between 250 and 370 nm, which allows us to track chirality ranges in the range ...

Did life’s predilection for so-called “left-handed” amino acids evolve as a quirk of prebiotic chemistry here on Earth? Or did biomolecules’ reliance on single “chirality” or ...

Fig. 3: Chiral amino acids. L-and D-amino acids are same in molecular weight, bond angle, bond length, but different in characteristics. Only L-amino acids have been regarded to be present in the ...
