The Chemistry of Carbon Carbon is the most versatile element
Can form up to 4 bonds at one time. Carbon may also form bonds with
other Carbons allowing for unlimited chain lengths -= May form
Single -, Double =, or Triple bonds with other Carbons Can even
fold over forming rings
Slide 3
All compounds can be classified into 2 broad categories:
Organic compounds- Contain carbon and hydrogen atoms Inorganic
compounds- Can have one or the other, but do not contain both
carbon and hydrogen atoms Most of your bodys molecules are organic
compounds.
Slide 4
How are biomolecules made? Macromolecules are built from small
organic compounds the same way a railroad train is built, by
linking a lot of smaller units together into long chains. Large
carbon compounds are built up from smaller simpler molecules called
monomers (mono = one )
Slide 5
How are biomolecules made? Monomers can bind to one another to
form complex molecules known as polymers (poly = many) A polymer
consists of repeated, linked units, which can also bind forming
large polymers called Macromolecules. (macro = large )
Slide 6
How are biomolecules made How are biomolecules made? Monomers
link to form polymers through a chemical reaction called a
condensation reaction or dehydration synthesis. During the
formation of polymers, Water (H 2 O), is released or is a
by-product of the reaction.
Slide 7
How are biomolecules made? The breakdown of some complex
molecules, such as polymers, occurs through a process known as
hydrolysis. Hydrolysis is the reverse of a condensation reaction.
The addition of water, to some polymers can break the bonds that
hold them together.
Slide 8
How are biomolecules made? Monomers Polymer
Slide 9
Types of Biomolecules There are four main types of
macromolecules found in living organisms: 1. Carbohydrates 2.
Lipids 3. Nucleic Acids 4. Proteins
Slide 10
A quick source of energy!!
Slide 11
What elements are carbs composed of? Carbon (C), Hydrogen (H)
and Oxygen(O) In a ratio of C : H : O 1 : 2 : 1 Example: Glucose C
6 H 12 O 6 6 1 : 2 : 1 For every 1 Carbon (C) You will have 2
Hydrogens (H) and 1 Oxygen (O).
Slide 12
Carbohydrate Monomers Carbohydrate Monomers (Building Blocks)
Monosaccharides: commonly found in rings Mono=one, Saccharide=sugar
Monosaccharides are simple sugars Examples: Glucose: commonly found
in blood of animals Galactose: a simple sugar found in milk
Fructose: commonly found in fruit
Slide 13
Carbohydrate Monomers (Building Blocks) Glucose
Slide 14
Carbohydrate Polymers Polysaccharides are carbohydrates formed
from linking individual sugars together. They can be very large and
complex, or they can be small and made up of only two monomers
linked together. These are called Disaccharides Polysaccharides:
Poly=Many, Saccharide=sugar
Slide 15
Carbohydrate Polymers Disaccharides: Poly=Two, Saccharide=sugar
Disaccharides contain 2 monosaccharides joined by dehydration
synthesis.
Slide 16
Carbohydrate Polymers Dissacharide Examples: Lactose: Found in
Milk Made up of Galactose + Glucose Sucrose: Table Sugar Made up of
Fructose + Galactose
Slide 17
Carbohydrate Polymers Complex Carb (Larger polysaccharide)
examples Starch: a form of glucose in plants (breads, pasta,
potatoes)
Slide 18
Carbohydrate Polymers Complex Carb (Larger polysaccharide)
examples Cellulose: contained in the cell walls of plants; gives
strength and rigidity to plant cells.
Slide 19
Carbohydrate Polymers Complex Carb (Larger polysaccharide)
examples Glycogen: a common storage form of glucose in animals
(stored in the muscles and liver to be used as quick energy)
Slide 20
Slide 21
What elements are Lipids composed of? Carbon (C) and Hydrogen
(H) Lots of Hydrogen!!!!!
Slide 22
Important Lipid Facts Lipids are Fats, Oils and Waxes Lipids do
not dissolve in water
Slide 23
Important Lipid Facts Lipids usually serve one of three
functions: Energy storage When carbs have been used up we use fatty
acids for energy.
Slide 24
Important Lipid Facts Lipids usually serve one of three
functions: structural support in cell membranes
(phospholipids)
Slide 25
Important Lipid Facts Lipids usually serve one of three
functions: Serve as messengers Steroids are lipids that carry
messages through the bloodstream.
Slide 26
Lipid Monomers? Fatty acids are the building blocks (or
monomers) that make up most lipids. Fatty acids are classified as
either saturated or unsaturated. Lipids do not have true
monomers
Slide 27
Lipid Monomers? How do you tell the difference? Saturated fatty
acids have NO DOUBLE BONDS!! They have the maximum number of bonds
possible, they are full (of hydrogen). Saturated fats are usually
solid at room temperature, and most come from animal products. Can
you think of some examples?
Slide 28
Lipid Monomers? How do you tell the difference? Unsaturated
fatty acids have double bond(s) in the carbon chain and are not
full. Most unsaturated fats are liquid at room temperature, and are
usually referred to as oils. Can you think of some examples?
Slide 29
Lipid Polymers A common lipid that contains fatty acids is a
Triglyceride. They are composed of a glycerol linked to three fatty
acids (in the shape of an E) by condensation reaction.
Slide 30
Store and transmit hereditary and genetic information.
Slide 31
What elements are Nucleic Acids composed of? Carbon (C),
Hydrogen (H),Oxygen(O), Nitrogen (N) and Phosphorous (P)
Slide 32
Nucleic Acid Monomers (Building Blocks) Nucleotides are the
building blocks (or monomers) that make up most nucleic acids.
Nucleotides consist of sugar(pentose) + nitrogenous base +
phosphate
Slide 33
Nucleic Acid Polymers Three main types of nucleic acids 1. DNA
= Deoxyribonucleic acid Instructions which code for protein
synthesis
Slide 34
Nucleic Acid Polymers Three main types of nucleic acids 2. RNA
= Ribonucleic acid Is the genetic information inside the nucleus of
cells
Slide 35
Nucleic Acid Polymers Three main types of nucleic acids 3. ATP
= Adenosine triphosphate ATP has a slightly different structure
than DNA and RNA. It contains a base + sugar + three phosphates ATP
is used as energy for the cell
Slide 36
Construction materials for body parts like bones, muscles and
blood. Fight disease Regulate cell Processes
Slide 37
What elements are Proteins composed of? Carbon (C), Hydrogen
(H),Oxygen(O), and Nitrogen (N)
Slide 38
Protein Monomers (Building Blocks) Amino acids are the building
blocks that make up most proteins There are 20 different kinds of
amino acids that humans use. Composed of : An Amino Group ( -NH 2 )
& A Carboxyl Group (-COOH)

Protein Examples One important group of proteins Enzymes
Enzymes help control chemical reactions by acting as catalysts.
Catalysts speed up reactions by lowering activation energy.
Slide 41
Special Proteins One important group of proteins Enzymes
Proteins that catalyze chemical reactions. Catalyze: increase the
rates of
Slide 42
Special Proteins Enzymes help control chemical reactions by
acting as catalysts. Catalysts speed up reactions by lowering
activation energy. Activation Energy: the minimum energy required
to start a chemical reaction.
Slide 43
Special Proteins Enzymes speed up the rate of reaction by
DECREASING the ACTIVATION ENERGY
Slide 44
Enzymes the speed of reactions that would otherwise occur
slowly. increase
Slide 45
Each enzyme has a certain job and does only that job. Enzymes
are special proteins that build or break down materials inside or
outside the cell.
Slide 46
How are Enzymes used in the body??? DIGESTION INFLAMMATION
during digestion, intestinal cells produce enzymes, which split the
food into small molecules so they can be absorbed into the blood
enzymes are produced by neighboring cells, so that the blood
clotting process can happen and to remove destroyed tissue.
Slide 47
Enzymes and Homeostasis Temperature Temperatures above 40 C
(104 F) denature/destroy enzymes. pH Extremely high or low pH
values generally result in complete loss of activity for most
enzymes.
