2. OBJECTIVE SWBAT Compare the chemical structures of carbohydrates, lipids, protein, and nucleic acids, and relate their importance to living things.

3. Lab Tomorrow BE ON TIME!!!!!!!!

4. Homework! Write down in your agenda book! Write down everything you eat today. Breakfast, lunch, dinner and snacks. Write down which biomolecules make up the food. You cannot participate in the lab until this is done.

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

6. Dissecting A Nutrition Label Fats Carbohydrates Protein Vitamins & Minerals

7. 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

8. Polymers large compounds of linked carbohydrates, proteins, lipids, and nucleic acids are called polymers These large organic compounds are called biomolecules.

9. 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!

10. BIOMOLECULEMADE OF… EXTRA INFOEXAMPLES CARBOHYDRATES (sugars and starches) LIPIDS/FATS PROTEINS NUCLEIC ACIDS

11. 1. Carbohydrates

12. CARBOHYDRATES SUGARS STARCHES Quick energy Long Term Energy

13. Carbohydrates A biomolecule composed of Carbon, Hydrogen, and Oxygen. Glucose (sugar) is a Carbohydrate Ratio: C 6 H 12 O 6

14. Runners “carbo-load” Carbs are a major source of energy!

15. Examples of Carbohydrates Fruits, vegetables, and grains

17. 1. ______________ are substances used by the body for energy and proper cell function. 2. Carbohydrates are used to _______and ________ energy. 3. The two major kinds of carbs are _______ and _________. 4. Sugars are called _________ carbs because they are the ___________ carb molecules. 5. ____________ is the most important fuel in plants and animals. 6.

Candy and sweets cause a spike in __________________. 12. ___________ ___________ digest slowly. 13. The more _______________ a carbohydrate the worse it is for you. 14. Anything is bad for you if you ____________________. fruits veggies grains blood simple blood sugar Whole grains processed over do it starches

19. 2. Lipids / Fats

20. Lipids (Fats) Made of C, H, & O in chains Examples: found in oils, butter, soaps & waxes Take Notes!

21. 3. Proteins

22. What Do Proteins Look Like? The building blocks of Proteins are amino acids. *Unlike Carbohydrates, proteins contain Nitrogen.

23. Proteins Needed for the growth and repair of body tissues

24. Where can we find proteins in living things? 1.) hair 2.) finger nails 3.) horns 4.) hoofs

25. Examples of Proteins Meat, egg, dairy, seeds, nuts, & beans

26. 4. Nucleic Acids

27. Nucleic Acids Carry genetic information in cells 2 types of nucleic acids 1.) DNA 2.) RNA

28. Nucleic Acid Structure Nucleic acids are made up of nucleotides DNA (deoxyribonucleic acid) – carries genetic information RNA (ribonucleic acid) – makes proteins

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

31. What did you learn? What are the 4 types of organic compounds? 1.) carbohydrates (sugars) 2.) lipids (fats) 3.) proteins 4.) nucleic acids

32. What are carbohydrates? main source of energy in body found in fruits, vegetables and grains aapples, corn, soda pop, potatoes, bread and broccoli

33. What are lipids (fats)? store energy in the body used as insulation around organs and tissues 2 types saturated and unsaturated found in fats, steroids and waxes examples, cooking oil, butter, ice cream and chips

34. What are proteins? are made from peptide bonds formed from amino acids there are 20 amino acids we make 10 naturally must consume the other 10 by eating poultry, fish, milk beef and nuts

35. Nucleic Acids All cells have nucleic acids 2 types are DNA and RNA

36. Homework: Keep a Food Journal Write down EVERY food you eat for 5 days!
