Organic Compounds

Organic Compounds

Compounds that contain CARBON are called organic.

Macromolecules are large organic molecules.

Slide 3

Carbon (C)

Carbon (C)

Carbon has 4 electrons in outer shell.

Carbon can form covalent bonds with as many as 4 other atoms (elements).

Usually with C, H, O or N.

Example: CH4(methane)

Macromolecules

Macromolecules

Large organic molecules.

Also called POLYMERS.

Made up of smaller building blocks called MONOMERS.

Examples:

1. Carbohydrates

2. Lipids

3. Proteins

4. Nucleic acids (DNA and RNA)
