What is the Meaning of Molecular Structure?

Molecular structure refers to the three-dimensional arrangement of atoms within a molecule, defining its specific shape, bond lengths, and bond angles. This precise spatial configuration is the fundamental determinant of a molecule's physical and chemical properties, including how it interacts with other biological molecules. For hormones and drugs, the molecular structure dictates its affinity for target receptors and its ultimate physiological effect.

What is the Origin of Molecular Structure?

The concept of molecular structure developed in the 19th and 20th centuries as chemists began to understand the nature of chemical bonding and the geometry of molecules. Techniques like X-ray crystallography and spectroscopy allowed for the empirical determination of these structures. The term is a descriptive combination of "molecular," relating to molecules, and "structure," referring to arrangement.

What is the Mechanism of Molecular Structure?

The mechanism by which structure dictates function is often described as a lock-and-key model, particularly relevant in endocrinology. A hormone's unique three-dimensional shape allows it to precisely fit into the binding pocket of its specific receptor protein. Alterations in the molecular structure, even subtle ones, can abolish binding or change the resulting cellular signal, leading to a loss of therapeutic efficacy or unintended side effects.
