Macromolecule

A macromolecule is a molecule with a molecular weight greater than 1000 atomic mass units.

Macromolecules are characterized by high molecular weight and complex chemical structure. They consist of a large number of atoms connected to each other by chemical bonds.

Macromolecules include natural and synthetic polymers, proteins, nucleic acids and other complex organic compounds. Their molecular weight can reach millions of atomic mass units.

A distinctive property of macromolecules is their colloidal nature. In solution, they form colloidal particles whose sizes range from 1 nm to 1 μm. Due to this, macromolecules exhibit typical colloidal properties - thixotropy, the ability to form gels and jellies.

Thus, macromolecules are high-molecular compounds with a complex chemical structure and colloidal properties. Their unique features determine the widespread use of macromolecules in various fields of science and technology.
