Study Notes
Large Biological Molecules
- Four main classes: carbohydrates, lipids, proteins, and nucleic acids.
- Polymers consist of smaller recurring units called monomers.
Polymerization and Hydrolysis
- Polymers are formed through dehydration reactions.
- Hydrolysis is the reaction that breaks down polymers into monomers.
Organic Compounds
- Carbon-based molecules are referred to as organic compounds.
Carbohydrates
- Simplest carbohydrates are monosaccharides, serving as building blocks for larger carbohydrates.
- Monosaccharide formula: CH2O or (CH2O)n; example: glucose (C6H12O6).
- Disaccharides are sugars formed from two monosaccharides.
- Polysaccharides are long chains of monosaccharides linked by dehydration reactions, such as starch, glycogen, and cellulose.
- Starch acts as a storage polysaccharide in plants, while glycogen is the animal equivalent.
- Cellulose provides structural support in plant cell walls.
Lipids
- Lipids are hydrophobic compounds, meaning they do not mix with water.
- Fats are large lipids composed of glycerol and fatty acids, primarily serving as energy-storage molecules.
- Saturated fats contain the maximum number of hydrogen atoms and are solid at room temperature; examples include butter.
- Unsaturated fats have fewer hydrogen atoms due to double bonds, remaining liquid at room temperature; examples include oils like olive oil and corn oil.
- Important lipids with various functions include phospholipids and steroids.
Proteins
- Proteins are polymers made from amino acid monomers.
- Structural proteins are found in hair, skin, and muscle.
- Polypeptides are chains of amino acids that fold into functional proteins.
- Denaturation occurs when polypeptide chains unravel, losing their specific shape and function.
Summary of Monomers and Functions
- Carbohydrates:
- Monomer: monosaccharide
- Function: short-term energy storage, plant structure
- Example: sucrose, starch, cellulose, glycogen
- Lipids:
- Monomer: fatty acids
- Function: long-term energy storage
- Example: triglycerides (fats), phospholipids, steroids
- Proteins:
- Monomer: amino acids
- Function: structural roles, enzymes
- Example: hair, skin, muscles, catalase
