Bellringer • Describe in detail what you see in the diagram. (Minimum 3 sentences) The digestive process is occurring. In order for organisms to live and function they require energy. Eating and digesting food provides the body with chemical energy in the form of ATP.
Schedule: Today you will be able to: Compare the structures & functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids. SE 9A • Pre-test • BiomoleculeHmwk Review IAN 11 • Biomolecule graphic organizer IAN 12 • Construct glucose molecule
Biomolecules You are what you eat!
Agenda • Carbohydrates • Proteins • Lipids • Comparing biomolecues • Constructing glucose molecules
Agenda • Carbohydrates • Proteins • Lipids • Comparing the biomolecules • McMush Lab
Carbohydrates aka… Sugar Starch Carbs
Breaks down into microscopic molecules Loaf of bread Bread crumbs Polysaccharide Monosaccharide Disaccharide
Structure Sugar Many Polysaccharide
Structure Sugar Two Di saccharide
Structure Sugar One Monosaccharide
Function • Provide QUICK energy to the body!
Bellchallenge: Explain what you think is happening here. (at least 3 sentences) Loaf of bread Bread crumbs Polysaccharide The diagram shows a picture of bread (starch). It also maps out the break down of carbohydrates from their most complex form (polysaccharide) to their least complex (monosaccharide). This process is called hydrolysis. Monosaccharide Disaccharide
Agenda • Bellchallenge: Carbohydrates • Carbohydrate/lipid Homework • Lipids • Test for Organic Compounds (Part A, C & D) • IAN Check (TOC & word wall) • Alternate assignment: • Pp. 48, 39, 43
Breaks down into microscopic molecules Fats, oils, waxes, steroids
Monomer: 3 fatty acids + glycerol
Polar head (&hormones) Non-Polar head Phospholipids & steroids join together w/proteins in the cell membrane
Function • Made mainly of carbon and hydrogen (few oxygen) • Fat best method of STORING • forms cell membranes • Insulates nerve cells (myelin) • Insulates body (maintains homeostasis)
Dehydration Synthesis • Combining single compounds into a complex one by removing water monosaccharide + monosaccharide ----> disaccharide + water C6H12O6 + C6H12O6 ----> C12H22O11 + H2O (Process forms disaccharides & polysaccharides)
Hydrolysis • Addition of WATER to a compound SPLITS it disaccharide + H2O ---> monosaccharide + monosaccharide C12H22O11 + H2O ---> C6H12O6+ C6H12O6
Bellchallenge:Describe what you see (at least 3 sentences) This is an amino acid. It is the monomer for a protein. It contains C, H, O and N. It has 3 groups: an amino group, an R-group, and a carboxyl group. The R-group is considered a variant group because it changes.
Friday 9/17/10 Agenda • Proteins • Test for Organic Substances (Parts C,D &E) • Complete analysis questions • HW: Venn Diagram- carbohydrates, lipids, proteins
Proteins aka…. Whey Protein Meat Polypeptide Peanut butter
Breaks down into microscopic molecules Polypeptide Meat Amino Acid Monomer: amino acid Polymer: polypeptide
Monomer: Amino Acids • Contains C, H, O, N • 20 types • Has both hydrophobic & hydrophylic ends • Differ in R-group • R-group can be acidic, basic or neutral • Makes polypeptide then makes proteins
Polymer: Polypeptide(peptide means bond) • Formed by dehydration synthesis • Sequence determined by DNA • 3-D and folds to take up less space
Function of Proteins • Provides us with building blocks for life! • Also regulate most functions in a cell. • Glycoproteins (antigens) • Combines w/DNA to form chromosomes • Turns genes on and off • Antibodies (fights disease)
Function of Proteins • Provides structure & strength (fibers) • Transports molecules in & out cells • Hemoglobin (transports O2) • Enzymes (speeds up rxns)- has –ase suffix • Acts as hormones (insulin)- many proteins have suffix of -in
Bellringer: Describe in detail what you see in the diagram. (minimum 3 sentences) This is a picture of ATP. ATP is one type of polymer of a nucleic acid. It is made of adenine, sugar, and 3 phosphate groups.
Monday 9/20/10 Agenda • Nucleic Acids • FinishTest for Organic Substances (Parts C,D &E) • Complete analysis questions • HWdue Friday: Venn Diagram- carbohydrates, lipids, proteins & nucleic acids
Nucleic Acids • Contains C, H, O, N, P • Monomer: NUCLEOTIDES • Nucleotidesconsist of 3 parts: 1. 5-Carbon Sugar 2. Phosphate Group 3. Nitrogenous Base
Nucleotide: Nitrogen Bases • 5 types • Cytosine • Guanine • Adenine • Thymine (in DNA only) • Uracil(in RNA only) • Purines or pyrimidines In DNA: In RNA: C-G C-G A-T A-U
Nucleotides: 5-carbon sugar and phosphate group • 2 types of sugars • Ribose (in RNA only) • Deoxyribose (in DNA only) • Phosphate group • Contains phosphorus & oxygen • Polymer: polynucleotide deoxyribose ribose
Function Polypeptide: DNA (deoxyribonucleic acid) • contains the genetic code • stores & transmit heredity/genetic information • found in the nucleus (mitochondria) • Double stranded (double helix)
Function Polypeptide: RNA (ribonucleic acid) • Carries info from DNA to cell • Helps in protein synthesis • found in ribosomes & nucleoli • Single stranded
Polypeptide: ATP • Contains adenine, ribose sugar, 3 phosphates • Stores and releases energy

C-H bonds • Count the number of C-H bonds in your monosaccharide picture. • Count the number of C-H bonds in your saturated or unsaturated bond picture • Which biomolecule (carbs or fats) have more C-H bonds?
The number of C-H bonds = the amount of energy • The more C-H bonds a biomolecule has, the more energy it has! • Fats have the most energy because they have the most C-H bonds!
