What is Macromolecule?
A macromolecule is a very large molecule, typically with a molecular weight greater than 10,000 daltons, composed of many repeating structural units (monomers) covalently bonded together. Biological macromolecules include proteins, nucleic acids (DNA, RNA), polysaccharides, and lipids. Synthetic macromolecules include plastics, rubbers, and synthetic fibers. The study of macromolecules is called polymer chemistry or macromolecular chemistry.

Biological functions (enzymes, structural proteins, genetic information storage). Plastic and polymer manufacturing. Medical devices and implants. Drug delivery systems. Food industry (starches, proteins, gums). Textile fibers (nylon, polyester). Adhesives and coatings. Nanotechnology.
Biological macromolecules: generally safe. Synthetic polymers: bulk polymer generally inert; monomer residues may be toxic (e.g., vinyl chloride monomer is carcinogenic; acrylamide is neurotoxic). Polymer combustion generates toxic fumes. Microplastic contamination environmental concern.
