Step 1: Define Macromolecules.
Macromolecules are large molecules composed of smaller subunits (monomers) that are chemically bonded together to form a larger, more complex structure. These molecules have high molecular weights and can be organic or inorganic.
Step 2: Examples of Macromolecules.
Common examples of macromolecules include:
- Proteins: Made of amino acids linked by peptide bonds.
- Polysaccharides: Made of sugar molecules (e.g., starch, cellulose).
- Nucleic acids: DNA and RNA, made of nucleotides.
- Polymers: Synthetic macromolecules like plastic, made from repeated monomers.
Step 3: Importance of Macromolecules.
Macromolecules play essential roles in biological systems. For example, proteins function as enzymes, hormones, and structural components, while nucleic acids store and transfer genetic information.
Final Answer:
Macromolecules are large, complex molecules made up of smaller monomeric units. They are essential in biology and can include proteins, nucleic acids, and polymers.
