CO: I will understand and identify the structure and function of a carbohydrate. LO: I will write notes and build a carbohydrate.
Notes: Biomolecules Biomolecules are the molecules found in all living things. Biomolecules are organic compounds. – Organic compound contain the element carbon (C) – All living things contain carbon – A substance without carbon is called inorganic Elements to know: C = carbonN = nitrogen H = hydrogenP = phosphorus O = oxygen
Carbohydrate Structure:Functions: Monomer:Polymer: Circle or ring shaped Create a 1:2:1 ratio Elements: C, H, O Main source of immediate energy Good to know: Often known as simple (monomers) and complex (polymers) Monosaccharide Examples: glucose, sucrose Polysaccharide Examples: starch, cellulose
Making a Carbohydrate: 1.What monomer did you build? 2.What elements are present in your monomer? 3.How does the structure of your monomer allow it to complete its function?
Bellwork: Which of the following is/are not carbohydrates? C 6 H 12 O 6 C 12 H C 6 O 12 H 6 C 6 H 12 O 14 C 12 H
CO: I will understand and identify the structure and function of a lipid. I will compare it to a carbohydrate. LO: I will write notes and build a lipid. I will create a Venn Diagram to compare carbohydrates and lipids.
Lipids Structure:Functions: Monomer:Polymer: Chain shaped A backbone and 3 tails Elements: C, H, O Source for long term energy Primary component of the cell membrane (hydrophobic) Good to know: Saturated fats: contain single bonds Unsaturated fats: contain double bonds Fatty acids Triglyceride (lipid)
Making a Lipid: 1.What kind of lipid did you make, saturated or unsaturated? How do you know? 2.What elements are in the lipids? 3.The glycerol in a lipid is often referred to as the glycerol backbone. Why do you think that is? 4.How does the structure of a lipid determine its function?
Bellwork Examine the following pictures of steroids. What kind of biomolecule do you think they are? Why?
