The Fundamentals of Chiral Resolution: Why Chirality Matters

Leave a Comment / Chiral resolution, Chiral Separation / By / , ,

Lead Chirality, a term derived from the Greek word “cheir,” meaning hand, is a fundamental concept in chemistry and biology that refers to the geometric property of an object not being superimposable on its mirror image. Much like our hands, chiral molecules exist in pairs known as enantiomers, which are mirror images of each other but cannot be aligned perfectly. Despite having the same molecular composition, these enantiomers can behave differently in biological systems due …

Chiral Bioequivalence – An Explainer  

Leave a Comment / Chiral science, Chirality / By / , ,

Introduction Chirality, or “handedness,” is the unique property of molecules that exist as non-superimposable mirror images, known as enantiomers. Drugs that exhibit handedness are referred to as chiral drugs. Chiral medications consisting of an equal (1:1) mixture of enantiomers are called Racemic drugs. In drug development, chirality is incredibly important because most biological molecules, like enzymes and receptors, are chiral. This characteristic affects how a drug interacts with biological targets, leading to significant differences in …
