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
