4 types of Organic Compounds

• Carbohydrates
• Lipids
• Proteins
• Nucleic Acids

3
Carbohydrates

• Sugars starches
• Store and release energy
• C,H,O
• Monosaccharide simplest sugar
• Disaccharide 2 monosaccharides (glucose
  fructose sucrose)
• Polysaccharide polymers (starch,cellulose,
  glycogen)

4
Lipids

• Fats and oils
• C,H,O
• Insoluble in water
• Long-term energy storage, insulation, protective
  coatings
• Saturated fatssolid at room temp.
• Unsaturatedliquid at room temp.

5
Proteins

• Build structure carry out cell metabolism
• C,H,O,N
• Amino acids are the building blocks (20)
• Enzymes-speed up chemical reactions

6
Nucleic Acids

• DNA RNA
• Stores information in codes
• Nucleotides are building blocks
