Study Notes
Classes of Biological Macromolecules
- Glycogen is classified as a carbohydrate.
- Cholesterol belongs to the lipid class.
- RNA and genes are classified as nucleic acids.
- Collagen and hemoglobin are proteins.
- Triacylglycerides are lipids, while cellulose and chitin classify as carbohydrates.
- Enzymes are also proteins.
Polymerization and Structure
- Polymerization is the process of creating or breaking apart polymers.
- Disaccharides differ in the number of monosaccharides.
- Protein denaturation disrupts secondary and tertiary structures due to broken hydrogen bonds.
- Alpha helices are stabilized by hydrogen bonds and commonly found in fibrous proteins.
- Beta pleated sheets are characterized by folds stabilized by hydrogen bonds between polypeptide segments.
Macromolecules and Their Building Blocks
- Four main classes of large molecules: carbohydrates, proteins, lipids, and nucleic acids.
- Three of these classes (carbohydrates, proteins, nucleic acids) are considered macromolecules.
- Macromolecules are large molecules consisting of smaller units.
- Polymers are complex structures made up of subunits known as monomers.
Reactions Involving Monomers and Polymers
- Dehydration reactions connect monomers, removing H and OH to form water.
- Hydrolysis reactions break apart polymers.
- The number of water molecules released in dehydration reactions equals the number of subunits minus one.
- In the reaction involving glucose, water appears on the right side of the equation.
Monosaccharides and Disaccharides
- Glucose serves as a monomer, while the monomer of carbohydrates is monosaccharides.
- Most monosaccharides are multiples of CH2O.
- Disaccharides include sucrose, maltose, and lactose, each formed from specific monosaccharides.
- Sucrose consists of glucose and fructose, commonly found in table sugar.
- Maltose is made of two glucose units, found in malt sugar or beer.
- Lactose consists of glucose and galactose, primarily found in milk.
- The suffix -ose indicates a sugar.
Carbohydrate Linkages and Polysaccharides
- Glycosidic linkages are covalent bonds between monosaccharides formed via dehydration reactions.
- Two polysaccharide types are energy storage and structural.
- Starch (amylose) and glycogen serve as energy storage polysaccharides.
- Cellulose and chitin are examples of structural polysaccharides.
- Humans cannot digest cellulose due to the inability of enzymes to hydrolyze its beta linkages, caused by structural differences.
