1. Bell Ringer: 10/9/17  turn in hmwk
Objective: Test for proteins using Biurets solution and complete a data chart/question to show knowledge.
Question: Identify what tests are used for the following substances.
Glucose
Butter
Cellulose
Olive Oil
Fructose
Glycogen

2. Carb, Lipid, Draw

3. Carbohydrates
Both
Lipids
T-Chart Comparison

4. Proteins Subunits are amino acids
Made up of C, H, O, N, and sometimes S
Two types of proteins are structural and functional.
Function
Example
Structure/support
collagen
Fight infection
antibodies (immune system)
Transport
hemoglobin carries O2
Catalyst
Enzyme
Movement
actin & myosin in muscle

5. Amino Acids 20 different R groups form 20 different amino acids
Consists of…
Central carbon
Amino group
Carboxyl group
Hydrogen atom
R group
(Blue)
(Red)
(Green)
(Orange/yellow)
(Purple)
20 different R groups form 20 different amino acids

6. Linking Amino Acids
Condensation reaction/dehydration synthesis links amino group of one amino acid with carboxyl group of next
Forms a peptide bond between amino acids
Water forms as a by-product

7. Bonding in Proteins polypeptide 2 amino acids  dipeptide
More than 2 amino acids  ______________
DNA determines the sequence of amino acids in a protein or polypeptide chain.
Sequence of amino acids is unique to each protein
polypeptide

8. Protein Lab
Copy of lab at stations. Write information on lined sheet of paper.
Goggles, if it gets on your hands wash immediately.
Biurets = blue to purple
When finished cleaning have me check
Your lab station & grab one paper
Post Lab: Video & Questions on weebly.

9. Amino Acid/Protein Video: Hand in when finished.

2. How many different types of amino acids are there?
3. What elements are amino acids made out of?
4. Define hydrophobic.
5. What type of bonds are amino acids joined together by?
6. Does the shape/structure of a protein impact the role it plays in the body?
7. What role does hemoglobin play in our body?
