Bell Ringer 1 2 3 4 5 6

Bell Ringer: 1. 2. 3. 4. 5. 6. 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 H 20 Molecule - Label everything!

Macromolecules (Carbon Compounds)

Carbon Compounds –All Macromolecules are Carbon Compounds. –All living organisms have Carbon in them Four Main Groups » Carbohydrates » Lipids » Nucleic Acids » Proteins

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.

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 ex. (starch) • Food Source Examples: Sugar, Pasta, Bread

Molecular Structure Monosaccharide Polysaccharide

Analogy Monomer Polymer

Lipids • Facts: Not soluble in water, Many plants have a waxy coating made of lipids to help reduce water loss. • Elements: C, H • Function: Energy Storage, Component of cell membranes. • Monomer: Glycerol and a long Fatty Acid chain • Polymer: Lipid • Food Source Examples: oils, waxes, butter

Molecular Structure Example: Lard

Analogy Go Steelers!!!!!

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

What do they look like? Polymer Monomer 13

Analogy

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: Polypeptide • 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"
