CHE SIGNIFICA CHIRALITY IN INGLESE
chiralità
Chirality / kaɪrælɪtiː / è una proprietà di asimmetria importante in diversi rami della scienza. La parola chiralità deriva dal greco, χειρ, "mano", un oggetto chirale familiare. Un oggetto o un sistema è chirale se non è identico alla sua immagine speculare, cioè non può essere sovrapposto su di esso. Un oggetto chirale e la sua immagine speculare sono chiamati enantiomorfi o, quando si riferiscono a molecole, gli enantiomeri. Un oggetto non chirale è chiamato acirale e può essere sovrapposto alla sua immagine speculare. Il termine fu usato per la prima volta da Lord Kelvin nel 1893 nella seconda conferenza di Robert Boyle all'Università Oxford University Junior Scientific, pubblicata nel 1894. Chiamo qualsiasi figura geometrica o gruppo di punti "chirale" e dichiari di avere chiralità Se la sua immagine in uno specchio piano, idealmente realizzata, non può essere portata a coincidere con se stessa. Le mani umane sono forse il più universalmente riconosciuto esempio di chiralità: la mano sinistra è un'immagine a specchio non sovrapponibile della mano destra; Non importa come le due mani siano orientate, è impossibile coincidere tutte le caratteristiche principali di entrambe le mani.
definizione di chirality nel dizionario inglese
La definizione di chiralità nel dizionario è la configurazione o la prontezza di un composto chimico asimmetrico, otticamente attivo chiamato anche dissimmetria.
