Study Notes
Biological Macromolecules
- Four major classes: carbohydrates, proteins, lipids, nucleic acids.
Dehydration Synthesis
- Byproduct is water (H2O) during the combination of monomers to form polymers.
- Involves the removal of a hydroxyl group from one monomer and a hydrogen atom from another.
Bonding in Polymers
- Monomers form covalent bonds with each other to create polymers.
Composition of Biological Macromolecules
- Biological macromolecules are composed of carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus.
Definition of Dehydration Synthesis
- A biochemical process where monomers combine, releasing water and forming polymer chains.
Carbohydrates
- Stoichiometric formula: (CH2O)n, where n is the number of carbon atoms.
- Ratio in carbohydrate molecules: 1:2:1 (one carbon to two hydrogens to one oxygen).
Classification of Carbohydrates
- Classified into three subtypes: monosaccharides, oligosaccharides, polysaccharides.
Monosaccharides in Aqueous Solutions
- In aqueous solutions, monosaccharides typically exist in cyclic forms.
Hydroxyl Group Arrangements in Glucose
- Around the anomeric carbon in glucose, two different hydroxyl group arrangements can occur (α and β configurations).
