Molecular Recognition

Molecular recognition is the process where molecules identify and specifically bind to each other based on their shapes, sizes, and chemical properties. Think of it like a lock and key: only the right key (molecule) fits into the lock (target molecule). This selective binding is essential for biological functions such as enzyme activity, antibody response, and cell signaling. It relies on precise interactions like hydrogen bonds, van der Waals forces, and ionic bonds. Overall, molecular recognition ensures that biological molecules interact accurately, enabling life processes to proceed efficiently and correctly.
