NBpg. 26 Top Unit 2: Biochemistry Quick Write: (Top 1/2 of the page) Describe matter and how is matter an essential part of life? Everything that has mass and takes up space, is made of matter. Atoms make up molecules, which make up the substance of living things. Carbohydrates, proteins, nucleic acids, and lipids are four kinds of molecules that are especially important to the structure and function of organisms.

NBpg. 34 Warm Up What does pH stand for? Explain neutral.

pH is the Power of Hydrogen NBpg. 34 1 of 3 Page 8 EQ: Explain how water is the greatest solvent on Earth. (Q1) Water can split apart to create H+ and OH-. Acids have a higher concentration of Hydrogen ions (H+). pH scale 1-6. Neutral is a balance of the ions. pH scale 7. Bases have a higher concentration of Hydroxide ions (OH-). pH scale 8-14. *Charged particles can interfere with chemical bonds and cause damage.

pH is the Power of Hydrogen (Cont.) NBpg. 34 pH is the Power of Hydrogen (Cont.) 2 of 3 Page 8 (Q2) Read Only: Not just Chemistry, but in Biology too… Buffer keeps solutions at a steady pH. If basic (OH-), then (H+) is added If acidic (H+), then (OH-) is added Creating water molecules to bring it closer to neutral. In organisms: blood or cytoplasm are the “solutions” in which ions are floating in, like electrolytes. The human body has two common buffers: carbonic acid (H2CO3) releases extra H+ ions, and bicarbonate ion (HCO3-) absorbs extra H+ ions. This function brings internal balance (Homeostasis).

pH is the Power of Hydrogen (Cont.) NBpg. 34 3 of 3 Page 8 A mixture is 2+ molecules that are physically mixed together - not chemically combined. A solution is 2+ molecules that are evenly distributed throughout the solution. - can not be separated. Substance which dissolves = solvent Substance that is dissolved = solute.

Tuesday: Mystery Powder Lab PG 47: Mystery Powder Lab Data Keep in Mind… Table Pg 46: Mystery Powder Lab Intro Intro: Procedures of each Test Test 1 2 3 4

Identify the Mystery Powder NBpg46 Mystery Lab Intro and Procedures Introduction: Biochemists often use simple chemical tests to identify substances present in our bodies. This part of the lab will test various powders to determine whether they contain carbohydrates (simple sugars and starch), lipids, or protein. Procedures: See handout: Simple Sugar (Glucose) Complex Sugar (Starch) Protein Lipids Keep in Mind: There are 6 powders that contain macromolecules. For each powder, you need to conduct each test for positive or negative results. A sample size is a pinch, and only 2-3 drops of indicator is needed to see results. Record your observations and infer what the mystery powders are based on the results. Identify the Mystery Powder Glucose Test +/- Starch Test Protein Test Lipid Test Control Water   _   _ _ 1. ______   2. ______ 3. ______ 4. ______ 5. ______ 6. ______

TEST FOR STARCH (polysaccharides) Add a small sample of the 5 substances Add 1-2 drops of IODINE solution to each well A positive test for starch is a color change to DARK BLUE OR BLACK. Be sure to look at the food color, NOT the liquid. Record the final color for each well and indicate whether the powder is positive (+) or negative (-) . Clean and dry the tray before the next test.   TEST FOR PROTEIN (Amino Acids) Add 5-8 drops of BUIRETS to each well. A positive protein test is a change of the liquid to a PURPLISH color. Record the final color for each well and indicate whether the powder is positive (+) or negative (-) . TEST FOR LIPIDS (Paper ) Add a small sample of the 5 substances to a piece of brown paper Rub the sample into the paper, and blot off excess sample. Let dry for 5-10 mins. A positive protein test will change the brown paper to a translucent color. Record the final color for each well and indicate whether the powder is positive (+) or negative (-) . Trash the paper when finished recording.  TEST FOR SIMPLE SUGARS (monosaccharides) Add a small sample to a test tube= 5 samples = 5 test tubes. Add 2-4 drops of BENEDICT SOLUTION to the test tube + HEAT (CAREFUL) A positive test for a simple sugar is a color change to GREEN, ORANGE, RED, OR YELLOW. Record the final color for each well and indicate whether the powder is positive (+) or negative (-) Clean and dry the test tubes before the next test.
