• Turn in your enzyme lab from yesterday into the
box in the back.
• Pick up handout from back and fill out what you
know.
• SHOW ME your homework (graphic organizer) for
credit NOW!
• Take out your
notebook and turn to the page where it contains
the proteins notes

• Job – provide structure & long term energy.
• Atoms – C,H,O,P,N
• Monomers – nucleotides (phosphate group,
sugar, nitrogenous base)
– Nitrogenous bases: adenine, guanine, cytosine,
thymine & uracil
• Polymers – none
• Macromolecule – nucleic acids
– DNA & RNA
• Job – store and transmit genetic information.
• Atoms – C,H,O, (1:2:1 ratio) C6 H12O6
• Monomers – monosaccharide C6 H12O6
– Glucose, galactose & fructose
• Polymers – disaccharide
– Sucrose, maltose and lactose
• Macromolecule – carbohydrate
– Starch, glycogen, cellulose, chitin
• Job – store & provide “quick” energy & provide
structure
• Atoms – C,H,O,N
• Monomers – amino acid (20 different types)
• Polymers – amino acid + amino acid =
dipeptide
• Macromolecule – protein
– Keratin, collagen, catalase, insulin, hemoglobin
• Job – Too many! 250,000 – one million
different types of protein in the human body! 8
categories:
– S3CDETT – structural, storage, signal, contractile,
defense, enzymes, transport, transcript
• Explain the ratio of carbon to hydrogen to oxygen
in carbohydrates. Use the simplest sugar or the
monosaccharide.
• All carbohydrates contain the atoms – C,H,O,
• All carbohydrates will have (1:2:1 ratio) C6 H12 O6
• The monomers, monosaccharide have the
simplest ratio - C6 H12 O6
– Examples include : Glucose, galactose & fructose
• Regarding its structure, how is a saturated
fatty acid different from a unsaturated fatty
acid? From a polyunsaturated fatty acid?
• Saturated fatty acids have carbons connected
to other carbons with a single bond.
Saturated fatty acids are solid at room
temperature.
• Unsaturated fatty acids have at least 1 double bond
joining one carbon to another carbon.
• Unsaturated fatty acids are not solid at room
temperature.
• Polyunsaturated have MANY double bonds in the
fatty acid chain. Polyunsaturated fatty acids are
liquid at room temperature.
• The monomers of nucleic acid are nucleotides. A
nucleotide has 3 components . Explain how
adenine, guanine, cytosine, thymine and uracil
influences the nucleotide.
• The 3 components are phosphate group, a sugar,
and a nitrogenous base. The nitrogenous base can
be one of the following: adenine, guanine,
cytosine, thymine, or uracil
• An amino acid has 5 components. What are
the five components. Also explain how it is
possible that the human body may have
almost a million different types of protein.
• An amino acid is composed of an amine
group, hydrogen, carboxyl group, central
carbon and a “R” group.
• 20 different amino acids…
• There are 8 different categories of proteins. Identify them and explain the
function of each category.
• S3CDETT
– “S” – storage: This type of proteins are found in seeds and eggs. Provides a source
of amino acids for developing plants and animals.
– “S” – signal: This type of proteins are responsible for cell communication. Includes
insulin & other hormones
– “C” – contractile: found mostly in muscle; Responsible for movement. Includes
actin and myosin
– “D” – defense: Proteins used by the immune system to identify and neutralize
foreign objects such as bacteria and viruses. Example includes antibiodies
– “E” – enzymes: biological catalysis that speed up chemical reactions.
– “T” – transport: Proteins involvement in the movement of ions, molecules and
macromolecules.
• Look for this handout for more information
about proteins!
• 1+23
3 + 8  11
• “building” molecules is called dehydration
synthesis or condensation reaction.
• Monosaccharide + monosaccharide  disacchriade + H2O
• Amino acid + Amino acid  dipepetide + H2O
• 95+4
20  11 + 9
• “breaking” molecules is called hydrolysis or
digestion.
• disacchriade + H2O Monosaccharide + monosaccharide
• dipepetide + H2O Amino acid + Amino acid
