Isomer

Meaning

An Isomer is a chemical compound that shares the exact same molecular formula as another compound but possesses a distinct arrangement of atoms in space, resulting in different chemical and physical properties. This structural variation is critical in biochemistry and endocrinology because even subtle changes in molecular geometry can profoundly alter a molecule’s biological activity, including its ability to bind to specific hormone receptors or be metabolized by specific enzymes. Understanding isomerism is essential for appreciating the precision of hormonal signaling.
