A Unit on Biomolecules Carbohydrates, Proteins, Lipids & Nucleic Acids You Are What You Eat! A Unit on Biomolecules Carbohydrates, 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

OBJECTIVE SWBAT 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 Take Notes! Topic: Biomolecules Carbohydrates Lipids Proteins Nucleic Acids *All are polymers *All are organic (C) compounds 4 organic compounds found in the human body

BIOMOLECULE MADE OF… EXTRA INFO EXAMPLES CARBOHYDRATES (sugars and starches) LIPIDS/FATS PROTEINS NUCLEIC ACIDS

1. Carbohydrates

CARBOHYDRATES STARCHES Long Term Energy SUGARS Quick 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… Take Notes! Made of C, H, & O in chains Examples: found in oils, butter, soaps & waxes

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 Take Notes! Examples: DNA or RNA Made of nucleotides Carry genetic information in cells Examples: DNA or RNA Nucleic Acids

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.
