0 Space-fillingmodel Structuralformula Ball-and-stickmodel H H H H C C H H H Methane H The 4 single bonds of carbon point to the corners of a tetrahedron. • Life’s molecular diversity is based on the properties of carbon • A carbon atom can form four covalent bonds • Allowing it to build large and diverse organic compounds Figure 3.1A
Fig. 4-3 Molecular Formula Structural Formula Ball-and-Stick Model Space-Filling Model Name (a) Methane (b) Ethane (c) Ethene (ethylene)
Carbon Configuration • Chain • Branched chain • Ring Structure
Propane Ethane Length. Carbon skeletons vary in length.
Butane Isobutane Branching. Skeletons may be unbranched or branched.
1-Butene 2-Butene Double bonds. Skeletons may have double bonds, which can vary in location.
Cyclohexane Benzene Skeletons may be arranged in rings. Rings.
Isomers • Isomers – same chemical formula, but different chemical arrangement • 3 different types of isomers
4 macromolecules • Carbohydrates • Lipids • Proteins • Nucleic Acids
Functional Groups! • These are like name tags for large macromolecule groups Glucose
Hydroxyl • Hydroxyl –OH (sometimes referred to as alcohol.) • Found in alcohol compounds • Example: Ethanol
Carbonyl • Keto =CO • Aldehyde -CHO
Carboxyl • Carboxyl -COOH found in acids
Amino • Amino -NH2 found in amino acids phenylalanine
Methyl • Methyl –CH3
Phosphate • Phosphate - PO4 • Unstable due to electronegativity • Found in ATP, DNA, RNA
