10. What does “biomolecule” mean?
“bio” = living, life
“molecule” = smallest unit of a chemical compound
Therefore…?

11. Biomolecules are the molecules found in all living things
Biomolecules are the molecules found in all living things. They are necessary for LIFE.

12. So…where do these come from. What are they made of
So…where do these come from? What are they made of? To figure that out, we have to start at the beginning…

13. 1. Biochemistry…The Basics
Matter: anything that has mass and takes up space
Element: matter made of only one type of atom
Atom: basic units of an element
only one type of element

14. The Fab Five Elements
In Biology this year, we will be focusing on 5 main elements. They are…
Carbon Hydrogen Oxygen Nitrogen Phosphorus

15. That’s 96.8% of your total body composition!
Notice just how much of the human body they compose
That’s 96.8% of your total body composition!

16. Carbon in Chemical Structures
Carbons are represented
By the letter C
Carbon is so common
in living organisms
that they can
sometimes be
omitted to save time. Anywhere there is a
corner without a letter,
that means a carbon is actually there.

17. Hydrogen in Chemical Structures
Hydrogen is represented
By the letter H

18. Nitrogen in Chemical Structures
Nitrogen is represented
By the letter N

19. Phosphorus in Chemical Structures
Phosphorus is represented
By the letter P

20. Directions: Label one example of each element on your practice page
Directions: Label one example of each element on your practice page. Color code the remaining elements C=green, H=blue, O=orange, N = pink, P=purple. Highlight the bonds in yellow.

21. Organic Compounds Compounds containing the element Carbon
Basis for living matter

22. Polymers (many parts) Monomers (one part) Macromolecules
Large molecules that are formed by joining smaller molecules
Polymers (many parts)
macromolecules made from repeating units of smaller molecules.
Monomers (one part)
a single unit which is bonded together

23. What is the monomer in the above polymer pictured?

24. What is the monomer in the above polymer pictured?

25. What is the monomer in the above polymer pictured?

26. What is the monomer in the above polymer pictured?

27. What is the monomer in the above polymer pictured?

28. Bonds, bonds, bonds! Molecules are atoms bonded together.
The bond stores energy.
When that bond is broken, energy can be released.

29. Chemical Reactions
Chemical reactions are how atoms bond together and break apart.
When a chemical reaction breaks a bond, energy can be release in the form of heat.

30. Parts of a Chemical Reaction
Arrow: “yields”, makes
C + O2  CO2
CO2
Reactants:
what goes INTO the chemical reaction, left side of arrow
Products:
what is produced from the reaction, right side of arrow
Chemical Reactions in a Cake

31. Biomolecules 4 major biomolecule: Carbohydrates Lipids Proteins
Nucleic acids
We find biomolecules in our FOOD!

32. Making/breaking polymers is part of metabolism.

33. Dehydration synthesis = a process through which polymers are formed from monomers through the removal of H2O.

34. Hydro=water
Lysis=cut
Hydrolysis = the process of breaking down polymers into monomers by the addition of H2O.
Hint: Think red rover

35. Carbon is represented by the letter C. …
Carbon is represented by the letter C! …. Circle that statement in with red and circle each Carbon in the molecules red.

36. Hydrogen is represented by the letter H
Hydrogen is represented by the letter H! … Circle that statement in Green and circle every Hydrogen on the molecular structures in green
