Presentation on theme: "Bell Ringer: Why is water considered a “polar” molecule?"— Presentation transcript:

1 Bell Ringer: Why is water considered a “polar” molecule?
Is the oxygen side positive or negative? Is the hydrogen side positive or negative? Define cohesion Define adhesion Draw a H20 Molecule - Label everything!

2 Joke of the Day:

3 Bell Ringer 1. Define Ionic Bond 2. Define Covalent Bond
3. What type of bond are the following: Fe2O3 CO2 4. Count the atoms -Ca(H2PO4)2

4 Macromolecules (Carbon Compounds)

5 Carbon Compounds Compound that contain carbon
All Macromolecules are Carbon Compounds. Four Main Groups Carbohydrates Lipids Nucleic Acids Proteins

6 Macromolecules Macromolecule: Giant molecule found in living things.
Monomers: (mono = one) The small individual units of the molecule Polymer: (poly = many) The large compound formed from many monomers Polymerization: process where large molecules are built from smaller ones.

7 Carbohydrates Facts: Elements in a ratio of 1:2:1. Elements: C,H,O
Function: main source of energy for living things Monomer: monosaccharide ex.(glucose) Polymer: polysaccharide (starch) Food Source Examples: Sugar, Pasta, Bread

8 Molecular Structure Monosaccharide Polysaccharide

9 Analogy Monomer Polymer

10 Lipids Facts: Not soluble in water Elements: C,H
Function: energy storage, component of cell membranes. Monomer: glycerol, fatty acids Polymer: lipid Food Source Examples: oils, waxes, butter

11 Molecular Structure Example: Lard

12 Analogy Go Lions!!!!!

13 Nucleic Acids Facts: Monomer made up Sugar, Phosphate, and Nitrogenous Base Elements: H,O,N,C,P Function: store and transmit genetic information. Monomer: nucleotide Polymer: nucleic acid Example: DNA, RNA

14 What do they look like? Polymer Monomer

15 Analogy

16 Proteins Facts: Every structure in your body is made up of proteins (skin, hair, nails, teeth, muscles, tendons etc.) Elements: C,H,O,N Function: Growth and Repair Monomer: Amino Acids Polymer: Proteins Food Source Examples: eggs, cheese, beans, meat the body can manufacture 14 of the 22 amino acids it needs. But the other 8 cannot be made by the body and must be obtained from the diet. These eight amino acids are called "essential amino acids"

17 Molecular Structure?

18 Analogy

19 Pass out charts and have students fill out

20 Macromolecule Flipbook
Front View (Closed) Pay attention to the details….. Don’t miss anything….. Must use color and be creative….. Proteins Carbs Macromolecules Inside Flipbook (Opened up) Lipids Nucleic Acids Molecular Structure of a Protein Molecular Structure of a Carb Amino Acid (monomer) Functions of Proteins Functions of Carbohydrates Back View (Closed) Food Sources for Carbs Food Sources for Proteins Elements: Elements: Functions of Lipids Functions of Nucleic Acids Examples: for Nucleic Acid Food Sources: Fats: Elements: Elements: Molecular Structure of a Lipid Molecular Structure of a Nucleic Acid Glycerol Fatty Acid Chain Your Name: Period: Nitrogenous Base Phosphate Group Deoxyrybose Sugar
