4 Organic Compounds
|
1. Carbs
2. Lipids 3. Proteins 4. Nucleic Acids |
|
|
Polymers
|
Chains of similar unites -- monomers
|
|
|
How are polymers synthesized?
|
By Dehydration Synthesis
= water is released |
|
|
How are polymers broken down?
|
By hydrolysis reactions
= water is added |
|
|
2 types of carbs
|
Sugars & Starches
|
|
|
3 classes of Carbs
|
1. Monosaccharides
2. Disaccharides 3. Polysaccharides |
|
|
Functions of Carbs
|
1. Source of Cellular fuel (glucose)
2. Structural Molecules (RNA) |
|
|
Monosaccharides
|
Simple Sugars
3-7 Carbon atoms |
|
|
Disaccharides
|
Double Sugars
Too big to pass through cell membranes |
|
|
Polysaccharides
|
Polymers of simple sugars
Not very soluble Ex: Glycogen is long branching chains of glucose |
|
|
Types of Lipis
|
1. Triglycerides
2. Phospholipids 3. Steroids 4. Eicosanoids |
|
|
Triglycerides
|
Function: Energy storage, insulation, protection
3 fatty acids bonded to a glycerol molecule ex: Solid fats and liquid oils |
|
|
Phospholipids
|
Function: important for cell membrane structure
Glycerol + 2 fatty acids & a Phosphorus group Head is polar, tail is nonpolar |
|
|
Steroids
|
Interlocking 4 ring structures
ex: Cholesterol, Vit D, steroid hormones, and bile salts |
