What are Monomers & Polymers?
Monomers- are small, single molecular units
like glucose and fructose.
Polymers- are chains of monomers strung
together. (by process of dehydration synthesis)
Using Carbohydrates as an example
• What are the monomers
of carbohydrates?
- Monosaccharides
• What are the polymers
of carbohydrates?
- Polysaccharides
