4. Four Groups of Organic Compounds in Living things
Group Name
Subunits
Functions
Examples
Carbohydrates
Lipids
Nucleic Acids
Proteins

5. What are carbohydrates?
Chemical Composition?
Examples?
Functions?
Ever heard of “carbo-loading” or “I’m watching my carbs?”

6. Carbohydrates
Consists of carbon, hydrogen, & oxygen (in a ratio of 1 C: 2 H: 1 O).
Main source of energy for living things!
Glucose – supplies energy to all cells
Cellulose – gives plants strength (plant cell wall!)
Starch – how plants store sugar
Glycogen – energy for muscle movement

7. Carbohydrates – “Sugars & Starches”
Monosaccharide- a simple sugar like glucose (blood sugar) or fructose.
Disaccharide- two sugar subunits linked together. A polymer of glucose & fructose make sucrose (table sugar).
Polysaccharide- the largest polymer made of many glucose subunits. Examples to know: starch, glycogen, and cellulose.

8. What happens when we mix oil and water?
What are Lipids?
Chemical Composition?
Examples?
Functions?
What happens when we mix oil and water?

9. Subunits: Glycerol & Fatty Acids
Lipids
Not soluble in water…
“oil & water don’t mix”
Waterproof coverings
Subunits: Glycerol & Fatty Acids
Fats and Oils – used for long-term E storage
Phospholipids – make up the cell membrane
Steroids – chemical messengers (hormones)

10. Lipids Saturated – SOLIDS - only C-C (butter)
Unsaturated – LIQUIDS - at least one C=C
Polyunsaturated – (canola oil)

11. What are Nucleic acids?
Chemical Composition?
Examples?
Functions?

12. Contains subunits called “nucleotides”
Nucleic acids
Contains subunits called “nucleotides”
Three parts: sugar, phosphate, nitrogen- containing base (DNA has A, T, G, C)
Transmit and store genetic information
RNA
DNA

13. What are Proteins?
Chemical Composition?
Examples?
Functions?

14. Most important fxn - Regulate cell processes
Proteins
Subunits - Amino acids
Most important fxn - Regulate cell processes
Have levels of organization to allow for 3D shape.
Ex: Enzymes
Amylase - Breaks down starch
into sugars.
