Chiraaliseen

Chiraaliseen is a Finnish term that translates to "chiral" in English, referring to a specific geometric property of molecules. A molecule is described as chiraaliseen if it is non-superimposable on its mirror image, much like a left hand is not superimposable on its right hand. This property is known as chirality.

Molecules that possess chirality exist as a pair of enantiomers. Enantiomers are stereoisomers that are mirror images of each other. They have the same chemical formula and connectivity but differ in their three-dimensional arrangement of atoms. This difference in spatial arrangement can lead to distinct physical and chemical properties, particularly in their interactions with other chiral entities, such as biological receptors or polarized light.

The presence of a chiral center, typically a carbon atom bonded to four different atoms or groups, is a common cause of chirality in organic molecules. However, chirality can also arise from other structural features. The concept of chiraaliseen is fundamental in organic chemistry, biochemistry, and pharmacology, as many biological molecules, including amino acids and sugars, are chiral. Understanding chirality is crucial for predicting and explaining the behavior of these molecules in biological systems and for designing new drugs and materials.
