Macromolecular Chemistry is the branch of chemistry that focuses on the study of macromolecules, which are large, complex molecules made up of smaller units called monomers. These macromolecules include natural substances like proteins and nucleic acids, as well as synthetic materials like plastics and rubber. Understanding their structure and properties is essential for various applications in materials science, biology, and medicine. Researchers in macromolecular chemistry explore how the arrangement of monomers affects the physical and chemical properties of the resulting macromolecules. This knowledge is crucial for developing new materials and improving existing ones, impacting industries such as pharmaceuticals, biotechnology, and polymer science.
