Small Molecules

Small molecules are low-molecular-weight chemical compounds, typically less than 900 Daltons, that can easily enter cells and interact with biological systems. They are often used in medicines because their size allows them to bind to specific proteins or enzymes, modifying their activity. Small molecules can include drugs like paracetamol or aspirin, as well as naturally occurring compounds. Their relatively simple structure and size facilitate synthesis, modification, and delivery, making them vital tools in pharmacology, biochemistry, and chemical biology for targeting biological processes effectively.
