Agenda: April 17/18th, 2013 1) Warm-up (10 min) 2) Create CHONPS foldable (10 min) 3) Set up notebook (5 min) 4) C-Notes: Introduction to Macromolecules (20 min) 5) Exit slip (5 min)
Warm-upIn your notebook: List what you already know about carbohydrates, lipids, proteins, and nucleic acids (where are they found? What do they look like? Why are they important?) Discuss with your group. Carbs: Lipids: Proteins: Nucleic Acids:You will receive a stamp at the end of this warm-up.
FoldableCreate a 6-layer foldable and label the 6 sections: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, and Sulfur. These are the 6 most common elements in organic chemistry. Duringthe notes you will write in which macromolecules each are found.
Set up C- Notes Topic: Introduction to Macromolecules Objective: Students know the characteristics of each of the 4 macromolecules
Organic Chemistry Organic chemistry is the study of compounds containing carbon. All organic molecules contain carbon. The reason carbon is so important is its ability to form bonds with four other atoms. This allows carbon to form a great variety of organic compounds. There are four basic groups of organic compounds in the body: 1) Carbohydrates 2) Lipids (fats) 3) Proteins 4) Nucleic acids.
Organic Substances of the BodyOrganic Compound Elements Building Blocks (you dont have to remember these)Carbohydrates Carbon, Hydrogen sugars and Oxygen (monosaccharides)Lipids Carbon, Hydrogen Glycerol and Fatty and Oxygen AcidsProteins Carbon, Hydrogen, Amino Acids Oxygen, Nitrogen, Phosphorus and SulfurNucleic Acids Carbon, Hydrogen, Nucleotides(DNA and RNA) Oxygen, Nitrogen and Phosphorus In your foldable, write down in which macromolecules you can find each element
Carbohydrates A carbohydrate contains carbon, hydrogen and oxygen and is another name for the sugars we taken in to provide most of our energy.
Lipids Lipids, or fats, are essential components of cells, especially cell membranes. Lipids also store energy, and can store twice the amount of energy as carbohydrates.
Proteins Proteins are complex molecules constructed from building blocks called amino acids. Amino acids join together to form proteins. Proteins are responsible for providing support in the cell, supporting movement through muscles, fighting infection, among other functions.
The Nucleic Acids – DNA and RNANucleic Acids have building blocks called nucleotides. There are 5 types, Thymine, Guanine, Cytosine, Adenine, and Uracil. These will be covered more in high school chemistry.
Exit Slip Tear out a sheet of paper and list 3 things you learned today. Turn in your sheet to the bucket On Friday you will have a lab where you will test whether the 4 macromolecules are present in foods.
