levoisomers

Levoisomers, also known as levorotatory isomers, are a class of stereoisomers that rotate the plane of polarized light to the left. Stereoisomers are molecules that have the same molecular formula and sequence of bonded atoms but differ in the three-dimensional arrangement of their atoms in space. Levoisomers are specifically those stereoisomers that exhibit levorotation, which is the rotation of the plane of polarized light to the left. This optical activity is a result of the asymmetric centers in the molecule, which can be either R or S configurations according to the Cahn-Ingold-Prelog rules. Levoisomers are important in various fields, including chemistry, biology, and pharmacology, where their optical properties can be used to identify and characterize compounds. For example, many biologically active compounds, such as amino acids and sugars, exist as levoisomers. The study of levoisomers is crucial for understanding the stereochemistry of organic compounds and their interactions with other molecules.
