Organic Macromolecules

Objective:• 9(A) compare the structures and functions of

different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids.

Main Idea

• Oraganisms are made up of carbon-based molecules

Organic chemistry

• Organic chemistry is the study of organic compounds – compounds that contain carbon.

• Carbon is a component of almost all biological molecules.• Carbon atoms bond together to form variety of important

organic compounds.

Macromolecules

• Macromolecules are large molecules that are formed by joining smaller organic molecules together.

• Polymers are molecules made from repeating units of identical or nearly identical compounds called monomers.

• Four major categories:– Carbohydrates– Lipids– Proteins– Nucleic acids
