ORGANIC CHEMISTRY
Learning Target: #2
Organic -comes from living matter
contains both C and H
Inorganic - comes from nonliving matter
does not contain both C and H
CARBON
Learning Target: #3
• The backbone of organic compounds
• Forms covalent bonds, and bonds with other
carbons
• Has 4 bonding sites
• Forms single, double, triple bonds
• Forms chains and rings
5 KEY TERMS: Learning Targets - #6 and #7
• FUNCTIONAL GROUPS - determine characteristics of
compounds/the part of the molecule involved in bonding
• Ex’s: -OH, hydroxyl group,
-COOH, carboxyl group,
-NH2, amino group
• Monomers - building blocks of organic compounds
• Polymers - large molecule formed from linking
monomers together
• Macromolecule - very large molecule (polymers joined)
• Isomer-molecules with same chem formula but
different structural formula
DEHYDRATION SYNTHESIS
Learning Target: #9
• The loss of water in
order to join 2
monomers, thus
forming a larger
molecule –polymer
• Also called a
condensation reaction
Hydrolysis
The addition of water to break apart
a polymer to create monomers

MONOSACCHARIDES
LearningTarget: #3, #6, #7, #8
• Monomer of carbs
• Elements- C, H, O (ratios
2:1, H:O)
• Ex’s: glucose, fructose,
galactose
• Formula- C6H12O6,
• Isomers
• Function-quick energy
• Tests-Benedicts-turns
orange, yellow, green, red
• Functional Group- -OH
(hydroxyl)
DISACCHARIDES
• 2 Sugar carbohydrate
• Formula- C12H22O11
• Functional groups-OH (hydroxyl)
• Tests-negative for both benedicts and iodine
• Ex’s-sucrose, maltose, lactose
Glycoside linkage to form disaccharides
Learning Target: #9
The two sugars are joined by condensation and
may be broken by hydrolysis

Different monosaccharides can
be used
• sucrose = glucose + fructose
• lactose = glucose + galactose
• maltose = glucose + glucose

CARBOHYDRATE FUNCTIONS
Learning Target: #8

•
Sugars (mono and disaccharides)
Maintenance of osmotic balance (e.g. salts in blood plasma,
plant cell turgidity);
transport of energy reserves (e.g. glucose in blood or sucrose
in sap);
energy substrate (respiration and photosynthesis);
energy store (sugar cane);
flavouring (fruits); reward (nectar);
precursors (building blocks) of polysaccharides, nucleotides
and amino acids

•
Many sugar carbohydrate
Formula- Cy(H2O)x
Tests-positive for Iodine (turns navy blue)
Function – short term storage of energy
Ex’s - glycogen (animal starch), starch (plants),
cellulose (plant building material)
