Homochirality（手性同质性）refers to a property of a system in which all chiral molecules have the same handedness. It is a concept in chemistry and biology that plays a crucial role in the functioning of living organisms.
Homochirality is a compound word that combines the Greek prefix "homo-" meaning "same" with "chirality" meaning "handedness". The word is pronounced as "hoh-moh-kai-ral-i-tee" with the stress on the second syllable.
In nature, homochirality is observed in the amino acids that make up proteins and the sugars that make up nucleic acids. All naturally occurring amino acids are of the L-configuration, while all naturally occurring sugars are of the D-configuration. This uniformity is essential for the proper folding and functioning of proteins and nucleic acids.
The concept of homochirality is also important in the study of the origins of life. It is hypothesized that homochirality played a crucial role in the emergence of life on Earth. The ability of living organisms to exclusively use L-amino acids and D-sugars is thought to have originated from a prebiotic environment that selectively favored the formation of one handedness over the other.
Synonyms for homochirality include "enantiomeric excess" and "chiral purity". Antonyms include "racemic mixture" and "chiral impurity".
Overall, homochirality is a fascinating concept that provides insights into the fundamental principles of chemistry and biology.
