Study Notes
Carbohydrate Properties
- Hydrophobicity: Carbohydrates with a low affinity for water are often characterized by a non-polar structure. This lack of polarity results in their low water solubility and tendency to repel water molecules.
DNA Structure
- Nucleic Acid: DNA (deoxyribonucleic acid) is classified as a nucleic acid molecule, responsible for storing and transmitting genetic information.
RNA Structure
- Single-stranded: Unlike DNA, RNA (ribonucleic acid) is a single-stranded molecule, allowing it to fold into complex three-dimensional structures which contribute to its diverse functions in protein synthesis and cellular regulation.
DNA vs RNA
- Sugar Structure: A key difference between DNA and RNA lies in the sugar molecules that form their backbone. DNA contains deoxyribose while RNA contains ribose, a sugar with an extra hydroxyl group.
Biomolecule Classifications
- Lipids: Lipids, a diverse group of biomolecules, do not include carbohydrates as part of their classification. They are characterized by their hydrophobic nature and serve crucial roles in energy storage, cell membrane structure, and signaling.
