1. What to look for…..
For Proteins look for NH2 and COOH, the test will not have an “R”
For Carbohydrates look for a bunch of OH
For Lipids look for long hydrocarbon chains (a bunch of carbons surrounded by hydrogens)
For Nucleic Acids look for the 3 parts (a ring sugar, a part that has nitrogen, and a part that has phosphorus)
THE ANSWERS TO EACH IMAGE ARE IN THE “NOTES” AT THE BOTTOM OF EACH SLIDE WHEN IT IS NOT IN PRESENTATION MODE.

2. 1)
Nucleic Acid

3. 2)
Lipids- Phospholipid

4. 3)
Protein

5. 4)
Carbohydrate. It doesn’t look like how we would normally see them drawn, but look at the functional groups (-OH).

6. 5)
Protein- showing dehydration synthesis

7. 6)
Nucleic Acid

8. 7)
carbohydrate

9. 8)
Nucleic Acid

10. 9)
Carbohydrate- disaccharide

11. 10)
Lipid- phospholipid

12. 11)
protein

13. 12)
Lipid- triglyceride

14. 13)
Carbohydrate- polysaccharide

15. 14)
Nucleic Acid

16. 15)
protein

17. 16)
carbohydrate

18. 17)
Lipid- just the fatty acid tail

19. 18)
Protein

20. 19)
Nucleic Acid
