Controlling chemical mirror images

Chirality, while not a rarity in the world of molecules, is nevertheless a special property. If a molecule is chiral (from the Greek word chiros = hand), it exists in two mirrored versions that are very similar but not identical—like ...

Study builds on plausible scenario for origin of life on Earth

A relatively simple combination of naturally occurring sugars and amino acids offers a plausible route to the building blocks of life, according to a paper published in Nature Chemistry co-authored by a professor at the University ...

Video: The limonene myth

Limonene, a compound found in citrus fruits, has two enantiomers: mirror-image molecules that cannot be superimposed, like a left and right hand.

Chirality in real time

Distinguishing between left-handed and right-handed (chiral) molecules is crucial in chemistry and the life sciences, and is commonly achieved using a method called circular dichroism. However, during biochemical reactions, ...

Observing changes in the chirality of molecules in real time

Some molecules can exist in two mirror-image forms, similar to our hands. Although such so-called enantiomers have almost identical physical properties, they are not the same. The fact that they behave to each other like ...

Using corkscrew lasers to separate chiral molecules

Many of the molecular building blocks of life have two versions that are mirror images of one another, known as enantiomers. Although seemingly identical, the two enantiomers can have completely different chemical behaviour—a ...
