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!

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

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"
