Polymer vs Macromolecule
Differentiation between polymers and macromolecules.
The aggregation and dispersion of molecules have different shapes and qualities. Polymers and macromolecules are often confused. Now distinguish the similarities and differences to make sense.
Polymers are formed by the connection of small molecules through polymerization. The molecular structure is arranged in repeating units, which are connected like beads. This repeating unit is called a monomer. The monomers are firmly bonded by covalent bonds to form a long chain or network structure. The characteristics of polymers depend not only on the properties of the monomers, but also on the polymerization method and the length and number of branches of the chain. For example, common polyethylene, with ethylene as a monomer, is additively polymerized to obtain flexible and durable materials, which are widely used in packaging and pipe fields.
Macromolecules refer to a wider range and generally refer to molecules with huge relative molecular weight. These not only contain polymers, but also natural macromolecules, such as proteins and nucleic acids. Proteins are connected by amino acids with peptide bonds, have complex three-dimensional structures, and perform many functions in life activities, such as catalysis, transportation, and immunity. The formation of macromolecules is either caused by polymerization reactions or by other molecular interactions.
Compared with the two, polymers must be macromolecules because they are polymerized by many monomers and have large molecular weights. However, macromolecules are not all polymers. For example, proteins and nucleic acids are not simply repolymerized by monomers, and their structures and formation mechanisms are more complex. The structure of polymers is often more regular and is constructed with repeating units; the structure of macromolecules is diverse, either regular or irregular.
To sum up, although polymers and macromolecules intersect, they each have their own characteristics. Clarifying the differences between the two is of great benefit to the research and application of materials science, biochemistry and other fields. It can help researchers accurately select materials, deeply explore material mysteries, and contribute to the progress of science and technology and the improvement of life.
