Do NOW: What does this picture mean to you?
4
There are two categories of compounds: Organic Inorganic
5
Substances that are formed by the chemical combination of two or more elements Most abundant compound on Earth is ___________ water
6
Elements have very different properties “actions/appearances” than the compounds that they form. H = Hydrogen = gas O = Oxygen = gas H 2 O = water = liquid
7
Are expressed through formulas 1.Chemical formulas 2.Structural formulas C 12 H 22 O 11 C 6 H 12 O 6
8
The attraction of atoms that cause element to form compounds
9
is any member of a large class of chemical compounds whose molecules contain carbon and hydrogen Found in all living things Examples C 6 H 12 0 6 CH 4
10
Is any member of a large class of chemical compounds of molecules that contain earths elements Not capable of creating life, no combination makes life Examples NaCl H 2 O CO 2
11
Compounds Organic Inorganic Contains Carbon & Hydrogen always together! Example: C 6 H 12 O 6 glucose (sugar) Contains the earth’s element Example: H 2 O water
15
Organic Compounds can combine to produce macromolecules!!! Macromolecules “giant molecules” that are made of thousands or even hundreds of thousands of smaller molecules.
16
1. Nucleic Acids Importance: stores cellular information in the form of a code Elements: C, H, O, N, P Subunits : Nucleotides Each nucleotide contains: Nitrogenous base Phosphorus 5 Carbon Sugar Examples: DNA and RNA
17
Structural formula
18
2.Carbohydrates Building blocks: Monosaccharide's Aka simple sugars
19
Chemical Formulas: C 6 H 12 O 6 Glucose C 12 H 22 O 11 Sucrose (table sugar) Ratio 1:2:1
20
Source of short term & long term ENERGY and FOOD STORAGE Carbohydrate Functions
21
Carbohydrates come in many forms that are classified into three categories:
26
Summary simple sugars, only A sample of food containing one type of a large molecule was treated with a specific digestive enzyme. Nutrient tests performed on the resulting products showed the presence of simple sugars, only. Based on these test results, the original large molecules contained in the sample were molecules of…… STARCH!
27
PART 2
28
In plants, simple sugars are least likely to be 1. linked together to form proteins 2. broken down into carbon dioxide and water 3. used as a source of energy 4. stored in the form of starch molecules
29
?
30
3.Lipids Building blocks : One Glycerol molecule and three Fatty Acid molecules
31
Chemical Formulas: C 57 H 110 O 6 C 54 H 99 O 6 Ratio is greater than 1:2:1
32
Lipid Functions include energy storage, acting as structural components of cell membranes, insulation, and participating as important signaling molecules
33
Lipids make up fats, oils and waxes Lipids can be found in butter, olive oil, peanut oil, cheese, milk, animal fat
34
LIPIDS THAT ARE ARE CALLED FAT LIPIDS THAT ARE SOLID ARE CALLED FAT LIPIDS THAT ARE LIQUID ARE CALLED OIL
35
Greater than 2:1 ratio -OSE ending Ring shaped Final Summary 1. How can determine a lipid by chemical formula? 2. How can we identify a carbohydrate by name? 3. What is the usual structural shape of a carbohydrate molecule?
36
What substance could be represented by the letter X in the diagram below? 1. carbohydrates 2. ozone 3. carbon dioxide 4. water
37
Organic compounds, such as proteins and starches, are too A to diffuse into cells. Proteins are digested into B and starches are digested into C. 1. A-large, B-simple sugars, C-amino acids 2. A-small, B-simple sugars, C-amino acids 3. A-large, B-amino acids, C-simple sugars 4. A-small, B-amino acids, C-simple sugars
39
What substance could be represented by the letter X in the diagram below? 1. carbohydrates 2. ozone 3. carbon dioxide 4. water
40
DO Now: Complete “Bio-Chem. recall” numbers 1-10 Homework: Bio-Chem. Review Sheet
43
There are 20 different sorts of amino acid, each with slightly different properties Proteins are made up of chains of amino acids, and are often folded up into a ball shape.
44
An 'average' protein has about 250 amino acids in its chain. How many different combinations are there of 250 amino acids? Although there are billions and billions of possible combinations, actually there are less than 100,000 used in the human body according to the best estimates of the scientists.
46
Structural component (most abundant organic material in the cell) Cell communication (hormones) Growth and repair Control rate of chemical reactions (enzymes) Immune defense (antibodies) Energy source
51
What are the most important Function of Proteins? 1) Structural Material (most abundant organic material within the cell) 2) Muscle Tissue 3) Enzymes - control chemical reactions w/in organisms 4) Cell communication (hormones, neurotransmitters) 5) Immune response (antibodies) 6) Growth and repair
52
AIM: How are organic compounds created? Do Now: Using the following word combinations create one sentence for each. 1.Organic compound, carbon, element 2.Carbohydrates, building blocks, monosaccarhides 3.Lipids, energy, fats, oils
53
How are organic compounds created?
54
CHEMICAL REACTION The formation of or breaking of chemical bonds, usually represented by a word or chemical equation. Na + Cl NaCl H 2 + N 2 NH 3 H 2 + N 2 NH 3
55
Reactants Reactants = found on the left of the equation Arrow Arrow = “to make”; shows a reaction is taking place Products Products = found on the right side of the equation. Na + Cl NaCl H 2 + N 2 2NH 3
56
1. Dehydration synthesis Combining small organic compounds (subunits) to produce large organic compounds with the loss of water.
60
Examples of Disaccharides Sucrose = Fructose + Glucose Maltose = Glucose + Glucose Lactose = Glucose + Galactose
61
Breaking a Large Compound into Smaller compounds by adding water The reverse of dehydration synthesis!!!
62
Maltose + Water produces Glucose+Glucose 2 separate molecules of glucose
63
& What is this process called? HYDROLYSIS
