Cyclization

Cyclization is a chemical process where a chain-like molecule forms a loop, creating a ring structure. This occurs when the ends of a molecule connect through a chemical reaction, often facilitated by specific conditions or catalysts. Cyclization is important in biological systems, like forming ring-shaped molecules such as hormones or neurotransmitters, and in industrial chemistry to produce drugs, plastics, and other materials. It changes the properties of the original compound, often making it more stable or functionally different. Overall, cyclization transforms a linear arrangement into a closed loop, influencing the behavior and applications of the molecule.
