1. Bell Ringer Hand in homework to proper bin
Which scientist is responsible for binomial nomenclature?
What words to you associate with regulation? Identify an example of regulation.
Explain what biomagnification is.
You have a quiz after this.

2. BioChem Quiz #1
When finished hand into station #7 and answer these questions on lined paper
Differentiate between inorganic and organic compounds and identify four examples of each using the chemical and structural formula.
Explain the difference between atom, element, molecule, and compound.
All ____________________ end in –ose.
Define lipid, glycerol, fatty acid, saturated, unsaturated, phospholipid, hydrophobic, hydrophilic, and steroid.

3. Lipid Lab Class Set: Write answers on separate sheet of paper
Don’t Glob. You want a light layer of each test.
What does translucent mean?

4. Lipids Primary function  store LONG TERM energy Contain C, H, and O
Contain more C-H bonds than carbs  better energy source
Subunits are…
Glycerol (containing a hydroxyl group -OH)
Fatty acids (containing a hydrocarbon chain)
Combine to form a triglyceride

5. Types of Lipids
Fats
Phospholipids
Sterols
Waxes

6. Functions Long term energy storage Cell Membranes Cushion Organs
Insulates Body

7. Monomer - Triglycerides
3 fatty acids attached to 1 glycerol
Triglycerides are most common
Triglycerides store twice as much energy as complex carbs
Unsaturated  one or more double bonds
Saturated with only single bonds
Fatty acid
(unsat.)
Glycerol
Fatty Acid
(saturated)

8. Saturated vs. Unsaturated
- Most animal fats
Solid at room temperature
Limit amount in your diet
Contributes to heart disease
Plants, vegetables, & fish fats
Liquid at room temperature
Better choice in your diet.

9. Phospholipids Hydrophobic fatty acid tails
Phosphate head is hydrophilic (orange area)
Main component of cell membranes

10. Sterols 4 fused carbon rings with functional groups
Cholesterol: most common type in animals
Functions include: membrane components and hormones (testosterone & estrogen)

11. Waxes
Tightly packed long-chain fatty acids linked to long- chain alcohols or carbon rings
All repel water
Found on the outer covering of a leaf (cuticle)

12. Finish Lipid Lab
Answer Conclusion Questions on separate sheet of paper. Make sure to write down the lab questions and answer below.
Throw away brown paper bag when finished and wipe up lab station.
Return to seat with lab. We will be adding to it.

13. Comparison Chart
Create a chart comparing carbohydrates and lipids.
