Study Notes
Biological Macromolecules
- All organisms are made up of four major classes of large molecules: carbohydrates, lipids, proteins, and nucleic acids
- Large biological molecules are called macromolecules and they are complex
Polymers and Monomers
- A polymer is a large molecule composed of repeating units called monomers
- Carbohydrates, proteins, and nucleic acids are polymers
- Enzymes are specialized macromolecules that speed up chemical reactions, including the synthesis and breakdown of polymers
- Dehydration reaction joins monomers together by removing a water molecule
- Hydrolysis breaks down polymers by adding a water molecule to the bond
Carbohydrates
- Carbohydrates serve as fuel and building materials in organisms.
- The simplest carbohydrates are monosaccharides, or simple sugars.
- Carbohydrate macromolecules are polysaccharides, polymers composed of many sugar building blocks.
Monosaccharides
- Monosaccharides have molecular formulas that are usually multiples of CH2O.
- The most common monosaccharide is glucose (C6H12O6).
- Monosaccharides are classified based on:
- The location of the carbonyl group (aldose or ketose)
- The number of carbons in the carbon skeleton.
Disaccharides
- A disaccharide forms when a dehydration reaction joins two monosaccharides.
- The covalent bond between two monosaccharides is called a glycosidic linkage.
Polysaccharides
- Polysaccharides are polymers made up of many monosaccharides.
- They have diverse functions including:
- Storage - starch (plants) and glycogen (animals)
- Structural support - Cellulose in plants and chitin in animals.
