Study Notes
Key Definitions
- Monomer: A simple molecule serving as a building block for polymers.
- Polymer: A large molecule formed by the chain-like linkage of similar monomers.
Examples of Polymers
- Polysaccharides: Carbohydrates formed by multiple sugar units.
- Proteins: Composed of amino acids; vital for many biological functions.
- Nucleic Acids: DNA and RNA, essential for genetic information storage and transfer.
Macromolecules
- Definition: Large biological molecules crucial for various cellular functions and structures.
-
Examples:
- Polysaccharides (e.g., starch, glycogen)
- Proteins (also known as polypeptides)
- Nucleic Acids (also known as polynucleotides)
Monosaccharides
- Definition: Single sugar units with the general formula (CH2O)n.
-
Types:
- Trioses: 3-carbon sugars
- Pentoses: 5-carbon sugars, e.g., ribose and deoxyribose
- Hexoses: 6-carbon sugars, e.g., glucose, fructose, galactose
Disaccharides
- Definition: Molecules formed by two monosaccharides linked by a glycosidic bond.
Polysaccharides
- Definition: Large polymers made from numerous monosaccharide subunits, serving as energy storage or structural components in organisms.
