Do now! – Review these terms with a table partner. Give the definition, let partner guess the word. MONOMER POLYMER CARBOHYDRATE MONOSACCHARIDE POLYSACCHARIDE LIPID COHESION ADHESION SOLUTION ACID BASE PH SCALE

BREAD MOLD LAB CONCLUSION - Please do a final check on your bread. - If you can count colonies, terrific! Record numbers (quantitative). - If you can count colonies, terrific! Record numbers (quantitative). - For most of us, a colony count will not be possible. Describe what you see (qualitative). - For most of us, a colony count will not be possible. Describe what you see (qualitative). - On the back of your data sheet, state if you see a difference between NO H2O and WITH H2O groups.

Key Terms Solvent – a substance in which a solute is dissolved Solute - a substance dissolved in a solution Solution – a mixture in which one or more substances is mixed within another Suspension – particles suspended (temp.) in a liquid Mixture – two compounds physically combined pH – scale comparing H+ and OH- concentration in sol Acid – H+ in greater concentration than OH- ions; pr do Base – OH- ions in greater concentration than H+ Dissociation – separation of mol. or atom into ionic particles
9
The study of organic compounds or compounds that contain carbon- hydrogen bonds
10
4 valence electrons... So it can form 4 covalent bonds with other atoms It can bond with H, O, P, S, and N
12
It can also bond with other atoms
13
single doubletriple
14
Terms Macromolecules means the 4 molecules of life (large molecules), formed through polymerization. Polymerization – the joining of smaller compounds to make larger ones Smaller units called Monomers are joined together to form…. Polymers or large compounds made up of smaller monomers
16
Polymer
17
3. The four groups of organic compounds found in living things are..l _____________________ _____________________.
18
They are non-hydrocarbon part of the molecule And they are clusters of atoms that influence the properties of the molecules they compose Hydroxyl Group -OH Carboxyl Group -COOH Amino Group -NH 2 3 Examples:
19
Contain: Functional groups: C, H, and O -OH (hydroxyl) Function: Source of Energy and building block for structure
20
Monomer Polymer = Monosaccharide (simple sugar) = Disaccharides and polysaccharides Skip 7 lines
21
simple sugars contain C, H, & O in a 1:2:1 ratio Example: C 6 H 12 O 6 3 Most Common 1 2 1 1.Glucose 2.Fructose 3.Galactose = fuel for cells = sweetest = milk sugar http://www.insideweightloss.info/blog/diet-tips-%E2%80%93-all-about-sugar/
22
Check to make sure each bag has: 14 black (carbon) 9 blue (oxygen) 4 red (nitrogen) 32 white (hydrogen) 58 white tubes (bonds) 1 small clear plastic bag If you are missing any pieces or have extra, pick them up or return them to the bins on the side lab bench.
24
Isomer= compounds with the SAME chemical formula, but different structural formulas Example: glucose, fructose, and galactose are all isomers of each other... C 6 H 12 O 6
25
Draw two examples in your notes:
27
Is a double sugar formed when 2 monosaccharides combine in a dehydration synthesis rxn 3 Examples 1.Maltose 2.Sucrose 3.Lactose = glucose + glucose = glucose + fructose = glucose + galactose
29
Fructose
30
Is a complex molecule made of 3 or more monosaccharides 3 Types 1.starch 2.glycogen 3.cellulose = sugar storage in plants = sugar storage in animals (in muscles) = structural component to plant cells (cell wall)
32
Check to make sure each bag has: 14 black (carbon) 9 blue (oxygen) 4 red (nitrogen) 32 white (hydrogen) 58 white tubes (bonds) 1 small clear plastic bag If you are missing any pieces or have extra, pick them up or return them to the bins on the side lab bench.

Macromolecule Structure Elements Monomer Structure Polymer Structure FunctionExamples Draw Monomer Structure Carbohydrates Proteins Lipids Nucleic Acids
34
Contain: C, H, O, and N Function: 1. Structural component to living things (helps build muscle mass) 2. Control cell processes and reactions (enzymes)
35
Monomer Polymer = amino acid = protein (folded polypeptide chain) Skip 12 lines
36
Contains 2 functional groups -NH 2 (amino group) and -COOH (carboxyl group) General aa structure R-group = different for each type of amino acid There are 20 different amino acids
38
20 different amino acids: http://nobelprize.org/educational/medicine/dna/a/translation/aminoacids.html “Protein alphabet”
39
Amino acids join by a dehydration synthesis rxn to form dipeptides and polypeptides
40
Primary Structure 1. Form a chain of aa Secondary Structure 2. Twist or fold the chain of aa (alpha helix or pleated sheet) Tertiary structure 3. Fold the chain onto itself (globular subunit) Quaternary Structure 4. Bring 2 to 4 aa subunits together (Ho
41
Correct folding is critical. If conditions are not right (temp, pH), this process will not take place or can be reversed (denaturation) and proteins cannot function!
42
Enzymes are made of proteins. They help speed up reactions and are UNCHANGED by the reaction. Image from: http://www.cas.muohio.edu/~wilsonkg/old/gene2005/syllabus_F03_23.jpg
43
Contain:C, H, and O Function: 1. Store Energy 2. Component to cell membrane http://www.red-spirit-energy-healing.com/essential-fats.html
44
Building blocks (“monomer”): Glycerol and fatty acid
45
=long hydrocarbon chain with carboxyl group attached
46
--Saturated C are full of H (no double bonds) --Unsaturated C are NOT full of H (double bonds)
47
Types of Lipids (“polymers”): 3. Steriods 2. Phospholipid 1. Triglyceride
48
Contain: Functional groups: C, H, O, N, P None that we discussed Function: 1. Store and transmit info to carry out cell processes and make protein 2. Transmit genetic info from one generation to the next
49
Monomer Polymer = nucleotide = Nucleic acid 1. Sugar 2. Phosphate 3. Nitrogen base 2 types: 1. DNA 2. RNA Image from: http://www.yourdictionary.com/dna
50
Homework: 1. Table completion of molecule characteristics. 2. Carbohydrate worksheet
