Monomers

Definition

Monomers are small, basic molecular units that can join together to form larger molecules called polymers. They serve as the building blocks for biological macromolecules such as proteins, nucleic acids, and polysaccharides.

5 Must Know Facts For Your Next Test

1. Monomers combine through dehydration synthesis (condensation reactions) to form polymers.
2. Common monomers include amino acids (proteins), nucleotides (nucleic acids), and monosaccharides (carbohydrates).
3. The properties of a polymer depend on the types of monomers used and how they are connected.
4. Hydrolysis reactions break down polymers into their monomer units by adding water.
5. Enzymes play a crucial role in both the synthesis and breakdown of biological macromolecules.
