1 2-3 Carbon Compounds

2 The Chemistry of Carbon
Because of carbons 4 valence electrons it can form covalent bonds with many other elements (octet rule) 9/19/2018

3 Chemistry (cont) Plus, it can bond with itself Carboxylic Acid Ethane
Each line represents a pair of shared electrons 9/19/2018

4 More Carbon Carbon can have single, double or triple bonds 9/19/2018

5 Macromolecules Many molecules are made of thousands, if not hundreds of thousands of other molecules Large molecules Macro = large Micro = small Formed by a process called Polymerization 9/19/2018

6 More Macromolecules Polymers = many monomers joined together
mono = one poly = many 9/19/2018

7 9/19/2018

8 4 Macromolecules Four organic compounds formed through this idea of polymerization Carbohydrates (sugars – simple and complex) Lipids Nucleic Acids Proteins 9/19/2018

9 Carbohydrates Carbon + water = carbohydrate
Carbon, hydrogen, and oxygen Chemical formula ratio C H2O Main source of energy for living things 9/19/2018

10 Monosacharides Monomers = Monosaccharide ENERGY source
Glucose (blood sugar), fructose, galactose Simple sugars – “sweet” Upon digestion they don’t have to be broken down Associated with “sugar highs” – sugar is available immediately All have chemical formula C6H12O6 9/19/2018

11 Disaccharides Disaccharide = two mono’s put together
Table sugar = sucrose Milk sugar = lactose Relatively small Sweet – would enter bloodstream quite quickly Two monosaccharide molecules put together 9/19/2018

12 Polysaccharides Polysaccharide = “many” monosaccharide molecules bonded together Large macromolecules Can be 1000’s of glucose molecules long Starch = polysaccharide Glucose = monosaccharide 9/19/2018

13 Animal Polysaccharides
Glycogen (animal starch) Polysaccharide in animals that stores excess sugar. Stored in liver and muscles Released and broken down when glucose (mono) is low. Excess monosaccharides will be converted 9/19/2018

14 Polysaccharide in plants that forms cell walls
Plant Polysaccharide Cellulose (fiber) Polysaccharide in plants that forms cell walls Very rigid giving plants structure Can’t be digested by humans but great in our diet. 9/19/2018

15 Carb Lipid Protein Monomer Polymer Amino Acids Lipids Glycerol
(composed of) Protein Dissaccaride Polysaccharide Monosacchride Glycerol 3 Fatty Acids Lipids Amino Acids Proteins Polypeptide 9/19/2018

16 Lipids Mostly made from carbon and hydrogen
Can be used to store energy Important parts of biological membranes and waterproof coverings 9/19/2018

17 9/19/2018

18 Lipids Fats, oils, and waxes Used for cell membranes
Store energy (9 calories per gram vs. 4 calories for carbs) 9/19/2018

19 Saturated Vs Unsaturated
9/19/2018

20 Saturated Fats Solid at room temp 9/19/2018

21 Unsaturated Liquid at room temp 9/19/2018

22 Nucleic Acids Macromolecules containing H, O, N, C, and P
Made of nucleotides which consist of 5-carbon sugar, a phosphate group and a nitrogenous base Store and transmit hereditary or genetic information 2 kinds RNA DNA 9/19/2018

23 9/19/2018

24 Nucleic Acid Atoms (C, H, O, N, P) Sides of ladder = Sugar + Phosphate
Rungs of ladder = nitrogen bases Adenine (A) pairs with Thymine (T) Guanine (G) pairs with Cytosine (C) Nitrogen Base Nucleotide = monomers Deoxyribose sugar Phosphate 9/19/2018

25 Nucleic Acid Nucleic Acids store and transmit
hereditary or genetic info. Order of nitrogen base pairs Determines individual uniqueness (eyes, hair, disease, etc.) 9/19/2018

26 Deoxyribose Nucleic Acid Double Helix Two sided, Helix – twisted
DNA Molecule Deoxyribose Nucleic Acid Double Helix Two sided, Helix – twisted Found in our nucleus Contain genetic information coded in the sequence of nitrogen bases RNA molecule Ribose Nucleic Acid Contains sugar called ribose One sided P G C 9/19/2018

27 Proteins Macromolecules containing H, C, and O.
Polymers of amino acids 9/19/2018

28 Examples 9/19/2018

29 Amino Acids Polymers made up of monomers called amino acids.
20 different amino acids. Can be fit together in many different ways to make various functioning proteins Amino group Carboxyl group General structure Alanine Serine Amino acid amino acid amino acid protein 9/19/2018

32 Proteins Roles Rate of reactions and regulate cell processes
Form bone and muscle Transport substances in and out of cells Fight disease 9/19/2018

33 Review Carbon Compounds Carbohydrates Lipids Nucleic acids Proteins
include Carbohydrates Lipids Nucleic acids Proteins that consist of that consist of that consist of that consist of Sugars and starches Fats and oils Nucleotides Amino Acids which contain which contain which contain which contain Carbon, hydrogen, oxygen Carbon,hydrogen, oxygen, nitrogen, phosphorus hydrogen,oxygen, nitrogen, 9/19/2018
