Today you need: textbook, your notebook, pen or pencil, 1 colored paper, scissors & markers to shareBellwork: vocabulary • Monomer • Polymer • Carbohydrate • Lipid • Nucleic acid • protein
objectives • Students will explore organic compounds. • Students will compare and contrast the 4 major bio molecules through lecture, note-taking and construction of a foldable.
Some prefixes and a suffix……. • Micro- small • Macro- large • Mono- one • Bi- two • Poly - many
Carbon organic chemistry Carbon – part of all organic compounds (living things) Unique because – 4 valence electrons lets it bond to other molecules and itself (in single, double or triple bonds) to make large and complex structures
BIOMOLECULES • MACROMOLECULES • made by polymerization-large compounds built by joining smaller ones together. • Smaller units are called monomers. • 4 major molecules important to life. • Carbohydrates, lipids, nucleic acids and proteins.
CARBOHYDRATES • 1:2:1 RATIO • 1 Carbon: 2 Hydrogen: 1 Oxygen • Main source of energyfor living things • Also has structural purpose for living things. • Plant cells have cell walls made of cellulose • Animal cells store excess sugars as glycogen
LIPIDS • PrimailyFats • Made of Carbon and Hydrogen. • NOT soluble in water • doesn’t mix with water • Used to store energy • Part of the cellmembrane. • Saturated-Solid at room temperature. • No double bonds • Unsaturated-liquid at room temperature. Double bonds between Carbons.
NUCLEIC ACIDS • Composed of Hydrogen, Oxygen, Nitrogen, Carbon and Phosphorus. • Subunits are called nucleotides. • Store and transmit hereditary information. • Examples: DNA , RNA
PROTEINS • Composed of Nitrogen, Carbon, Hydrogen, and Oxygen. • Monomers are called amino acids • Control rate of reactions • Function in transport and formation of bone and muscle cells. • Folded shape is important in enzyme recognition process.
foldable • Let’s make a foldable of the 4 different biomolecules
