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 energy for living
things Also has structural purpose for
living things.1. Plant cells have cell walls
made of cellulose2. Animal cells store excess
sugars as glycogen
LIPIDS Primaily Fats Made of Carbon and Hydrogen. NOT soluble in water
doesn’t mix with water Used to store energy Part of the cell membrane. 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
