Lesson 3
Do not write this slide § Content to Master: § Describe the basic molecular structures and primary functions of the four categories of biological macromolecules § How We Will Get There: § List the four types of macromolecules § Describe the molecular structures of each macromolecule § Describe the primary function § Identify real life examples of each macromolecule § Compare and Contrast the characteristics of each group
§ Large molecules composed of smaller units § Called organic molecules because they are found in living things § Structure of the macromolecule determines the function
§ 4 main types of Macromolecules: 1. Carbohydrates: short-term energy 2. Lipids: Long-term energy 3. Proteins: Carry out reactions in the body 4. Nucleic Acids: Genetic Information
§ Subunits=monomers § “Mono” means one § Monomers together=polymers § Poly” means many § Process of building= Polymerization
§ Made of carbon, hydrogen, and oxygen § Ratio is 1: 2: 1 § Function= QUICK energy source § End in suffix –ose § Ring Structure (DRAW IT)
Monomer of Carbs § Monosaccharide § One sugar Polymers of Carbs • Disaccharide • Two sugars • Ex: Sugar, Lactose, Sucrose § Ex: Glucose • • Polysaccharides: Many sugars Ex: Starch, Cellulose (Plant Source) Ex: Glycogen (Animal Source)

• Identify the monomer for the carbohydrate group • Identify the polymer for the carbohydrate group Elements: Function: Ends in letters: Simple Chemical Common Words: Sugar, Starch Give 3 examples of good carbs Give 2 examples of bad carbs

§ Elements: Carbon, Hydrogen, Oxygen § Function= long term energy § Cannot dissolve in water because they are Nonpolar § E Shaped Structure (DRAW IT)
Monomer of Lipids § Glycerol § Fat Tails Polymers of Lipids § Triglycerides (fats) § Phospholipids
Triglycerides: § Three fatty tails § Glycerol molecule Two categories: § 1. Saturated Fat, Single bonds, Solid (animal) § 2. unsaturated fat, double bond, liquid (plant)
