1 Macromolecules Composed of several simple units

2 Macromolecules Composed of several simple units
Bond by one giving up a H+ and the other a OH- H + + OH- form water – Dehydration Synthesis Hydrolysis - Break apart units by adding a water

3 Carbon - shares e- to fill outer shell
- forms chains Organic Compounds – molecules with carbon - carbon bonds

4 Carbohydrates Elements - C, H, O Building Block:
Monosaccharides – one sugar ex. C6H12O6 – glucose, fructose, galactose, ribose

5 Disaccharides – two monosaccharides
·       Sucrose – table sugar ·       Lactose – in milk Polysaccharides – 3 or more monosaccharides ·       Glycogen – animals ·       Starch – plants ·       Cellulose – structural in plants Uses – quick energy (mono + disaccharides), - long energy (polysaccharides) - structural (polysaccharides)

6 Lipids Elements: C, H, O Three Types – all hydrophobic (do not mix with water) · Steroids – 4 fused rings sex hormones, cholesterol, chlorophyll · Waxes - chains bees wax, earwax · Fats – Building Blocks: glycerol and 3 fatty acids

7 Two Types of Fatty Acids

8 Two Types of Fatty Acids
Saturated Unsaturated

9 Two Types of Fatty Acids
Saturated Unsaturated Solid at Room Temp Liquid at Room Temp

10 Two Types of Fatty Acids
Saturated Unsaturated Solid at Room Temp Liquid at Room Temp Found mostly in

11 Two Types of Fatty Acids
Saturated Unsaturated Solid at Room Temp Liquid at Room Temp Found mostly in animals - butter, animal fat Found mostly in

12 Two Types of Fatty Acids
Saturated Unsaturated Solid at Room Temp Liquid at Room Temp Found mostly in animals - butter, animal fat Found mostly in plants -peanut oil, olive oil

13 Two Types of Fatty Acids
Saturated Unsaturated Solid at Room Temp Liquid at Room Temp Found mostly in animals - butter, animal fat Found mostly in plants -peanut oil, olive oil No Double bonds between carbons Double bonds between carbons

14 Uses - Energy Storage - Insulation - Hormones - Structural – phospholipids make up cell membrane

15 Protein Elements: C, H, O, N Building Block: amino acids (a.a.)
· Over 20 different a.a. The order and number of the a.a. dictates the properties of the protein

16

17

18 Protein Structure Primary – sequence of a.a. Secondary – chain forms helix or pleats Tertiary – folds Quarternary – two or more chains combine

19 Uses Structural – cartilage, tendons, hair Food source – egg white Regulatory – hormones (insulin) Enzymes - Catalyst, speeds up the reaction - Are specific and can only work on certain molecules

20 Nucleic Acids Elements: C, H, O, P, N Building Block: nucleotides
2 types of Nucleic Acids DNA – deoxyribonucleic acid RNA – ribonucleic acid Uses – Genetic Material

21 Isomers – compounds that differ in structure, but not composition
C6H12O6 Isomers – compounds that differ in structure, but not composition

22 Energy of Macromolecules is in the Bonds
Fat = cal/g

23 Energy of Macromolecules is in the Bonds
Fat = 9 cal/g Carbo =

24 Energy of Macromolecules is in the Bonds
Fat = 9 cal/g Carbo = 4 cal/g Protein =

25 Energy of Macromolecules is in the Bonds
Fat = 9 cal/g Carbo = 4 cal/g Protein = 4 cal/g
