Transcript of Macromolecules

And Function Macromolecules Structure Large Molecules that are formed by joining smaller organic molecules together. What is a Macromolecule? Polymers Monomers Biological Molecules Carbohydrates
Nucleic Acids Carbohydrates
Store energy and Provide Structural Support Lipids
Store Energy and Provide Barriers Proteins
Transport Substances, Speed up Reactions, Provide Structural Support, and Make Hormones Nucleic Acids
Store and Communicate Genetic Information Compounds composed of a ratio of
1 Carbon to 2 Hydrogens Simple Sugars-are known as monosaccharides Carbohydrate Facts Glucose What are two monosaccharides joined together called? Monosaccharide Monosaccharide Also made up of Carbon and Hydrogen atoms Lipids Triglycerides:
Fat if solid at room temperature
Oil if liquid at room temperature Diasaccharide Glycerol Smallest Basic Units of a Macromolecule Many monomers linked together consisting of nearly identical repeating units. Lipid Structure
Phosphate heads - Polar
Fatty Acid Tails - Nonpolar Hydrophillic Water loving Proteins Monomers of Proteins are Amino Acids Polymers: Polypeptides (lots of amino acids linked together) N C C H H H H O O R Variable Group Carboxyl Group Hydrogen Atom Amino Group Amino Acid Structure Primary Protein Polymer Structure 20 different amino acids Form chains Nucleic Acids Monomers: Nucleotides Polymers: Nucleic Acids Five Nucleotide Bases DNA

Four Bases of DNA
Adenine, Guanine, Cytosine, and Thymine RNA
Uracil DNA Structure Complimentary Base Pairing Nucleotide Structure HOMEWORK Macromolecule Review Hydrophobic Water Hating Structure and Function Polysaccharides Carbon
Important element All Living 18% Human body Protein Structure Amino acid sequence Functions Regulation Hormones Transport Hemoglobin Structure Hair and Nails Movement Muscle Fiber Defense Antibodies http://www.greatpacificmedia.com/ Lysine, Valine, Alanine Cereal Grains, Most foods, Meats ATP Nucleotide - 3 phosphate groups Carbon atoms can bond in Straight Chains, Branched Chains, or rings. Peptide bonds-join amino acids Phospholipid Bilayer Fats, Oils, Waxes, Steroids (cholesterol and hormones), and Water Proof Coating. Cell Membrane Lipids Chains, Branched, or Rings Deoxyribonucleic Acid
Ribonucleic Acid Responsible for Function Lactose Made up of how many monomers? Glucose and galactose Amino Acid Chain Combinations One Four Two Four Structural Forms of Proteins Primary Structure
