You Are What You Eat!

A Unit on BiomoleculesCarbohydrates, Proteins, Lipids & Nucleic Acids

What are organic compounds?

• most matter in your body is made of organic compounds

• organic compounds contain carbon

• carbon atoms covalently bond to other elements like H and O

• large compounds of linked carbohydrates, proteins, lipids, and nucleic acids are called polymers

OBJECTIVESWBAT Compare the

chemical structures of carbohydrates, lipids, protein, and nucleic acids, and relate their importance to living things.

What are organic compounds?

• most matter in your body is made of organic compounds

• organic compounds contain carbon

• carbon atoms covalently bond to other elements like H and O

Polymers

• large compounds of linked carbohydrates, proteins, lipids, and nucleic acids are called polymers

• These large organic compounds are called biomolecules.

4 organic compounds found in the human body

1. Carbohydrates

2. Lipids

3. Proteins

4. Nucleic Acids

*All are polymers*All are organic (C) compounds

Topic: Biomolecules Take Notes!

BIOMOLECULE MADE OF…

EXTRA INFO EXAMPLES

CARBOHYDRATES(sugars and

starches)

LIPIDS/FATS

PROTEINS

NUCLEIC ACIDS

1. Carbohydrates

CARBOHYDRATES

SUGARSSTARCHES

Quick energy

Long Term Energy

Carbohydrates (Made of…)

•A biomolecule composed of Carbon, Hydrogen, and Oxygen.

•Glucose (sugar) is a Carbohydrate

Ratio:

C6H12O6

Examples of Carbohydrates

Fruits, vegetables, and grains

2. Lipids / Fats

Lipids (Fats)

made of…• Made of C, H, & O in chains• Examples: found in oils, butter,

soaps & waxes

Take Notes!

3. Proteins

What Do Proteins Look Like?The building blocks of Proteins are amino acids.

*Unlike Carbohydrates, proteins contain Nitrogen. Extra info

Proteins (extra info)

Needed for the growth and repair of body tissues

Where can we find proteins in living things?

1.) hair

2.) finger nails

3.) horns

4.) hoofs

Examples of Proteins

Meat, egg, dairy, seeds, nuts, & beans

4. Nucleic Acids

Nucleic Acids

• Made of nucleotides• Carry genetic information in cells

• Examples: DNA or RNA

Take Notes!

Nucleic Acid Structure

• Nucleic acids are made up of nucleotides

• DNA (deoxyribonucleic acid) – carries genetic information

• RNA (ribonucleic acid) – makes proteins

OBJECTIVE• SWBAT differentiate between

the four biomolecules (carbohydrates, lipids, protein, and nucleic acids) by testing for their presence in the components of a Big Mac burger.
