|April 29, 2015
Summary
Parity-violating gravity may explain molecular chirality. This review explores gravitational potentials, their chiral properties, and experimental constraints, offering insights into homochirality origins.
Area of Science:
- Physics
- Quantum Chemistry
- Gravitational Physics
Background:
- Chirality is fundamental in molecular physics and biology.
- Parity violation in gravity is a theoretical possibility with potential implications for fundamental physics.
- Existing models of gravity do not fully explain the origin of homochirality.
Purpose of the Study:
- To review parity-violating gravitational potentials as sources of true and false chirality.
- To explore models extending general relativity with torsion that induce short-range chiral interactions.
- To discuss physical mechanisms, effects, and experimental constraints of gravitational parity violation.
Main Methods:
- Analysis of phenomenological long-range spin-dependent gravitational potentials.
- Investigation of extended general relativity models with torsion.
- Discussion of theoretical mechanisms and experimental constraints.
Main Results:
- Phenomenological potentials exhibit both true and false chiral terms.
- Extended models with torsion yield short-range, truly chiral interactions.
- Gravitational parity violation mechanisms and their experimental feasibility are discussed.
Conclusions:
- Parity-violating gravity offers a potential explanation for molecular homochirality.
- Further research in quantum chemistry is needed to explore these gravitational effects.
- Experimental verification of these chiral gravitational interactions is crucial.

18.2K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

32.7K
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

02:30Chirality at Nitrogen, Phosphorus, and Sulfur
7.5K
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.

5.4K
The concept of prochirality leads to the nomenclature of the individual faces of a molecule and plays a crucial role in the enantioselective reaction. It is a concept where two or more achiral molecules react to produce chiral products. A typical process is the reaction of an achiral ketone to generate a chiral alcohol. Here, the achiral reactant reacts with an achiral reducing agent, sodium borohydride, to generate an equimolar mixture of the chiral enantiomers of the product. For example, an...

02:25Molecules with Multiple Chiral Centers
16.6K
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2,3-diol have multiple chiral centers. A simple formula to predict the number of stereoisomers possible for a molecule with n chiral centers is 2n. However, there can be a lower number where some of the stereoisomers are...

00:58¹H NMR Chemical Shift Equivalence: Enantiotopic and Diastereotopic Protons
4.1K
Replacing each alpha-hydrogen in chloroethane by bromine (or a different functional group) yields a pair of enantiomers. Such protons are called prochiral or enantiotopic and are related by a mirror plane. Enantiotopic protons are chemically equivalent in an achiral environment. Because most proton NMR spectra are recorded using achiral solvents, enantiotopic hydrogens yield a single signal.
