| 19094536 | Monomer | The simple starting material or single unit from which a polymer is built. It refers to the repeat units that make up the polymer chains. A molecule that may react chemically to another molecule of the same type to form a larger molecule. | |
| 19094537 | Polymer | Compound made of several repeating units (monomers). A molecule composed of repeated subunits. Several smaller, similar units in a chain to create a larger molecule with new properties. | |
| 19094538 | 4 Macromolecules | Protein, carbohydrate, nucleic acid, lipid | |
| 19094539 | What are the monomers that make up proteins? | amino acids | |
| 19094540 | What are the monomers that make up carbohydrates? | monosaccharides, simple sugars | |
| 19094541 | What are the monomers that make up nucleic acids? | nucleotides | |
| 19094542 | Why are lipids not considered polymers? | Polymer = Several smaller, similar units in a chain to create a larger molecule with new properties. Lipids = have no single sub-unit | |
| 19094543 | Recognize the four macromolecules based on structural diagrams | Protein - CCN backbone, lipid - three chains (triglycerol), polysaccharide - multi rings connected, disaccharide - two carb rings connected | |
| 19094544 | What is the difference between mono, di, and polysaccharides? | mono = one simple sugar, di = two saccharides covalently linked, poly = sequence of monosaccharide and disaccharide units to make is longer/bigger | |
| 19094545 | What is the difference between saturated and unsaturated acids (fats)? | sat - solid at room temp, not essential, harder to digest, carbon atoms have a single bond between them and as many hydrogen atoms as possible are bonded to the carbon atoms, unsat - liquid at room temp, contains a carbon-carbon double bond | |
| 19094546 | What is the role of the dehydration synthesis in building up polymers? | an H from one carbohydrate and an OH from another are taken out. They form water. The two carbohydrates are then joined together by a bond called a glycosidic linkage. you build while taking water out | |
| 19094547 | What is the role of hydrolysis in breaking down polymers? | opposite of dehydration synthesis. add water to break down a molecule. | |
| 19094548 | How does Benedict's solution work and what does it test for? What does a positive result look like? | mix with food and heat. test of monosaccharides (simple sugars, glucose), light blue in color, turns to green, yellow/orange, or even red when heated in the presence of simple sugars | |
| 19094549 | How does Biuret work and what does it test for? What does a positive result look like? | shake with test food. protein indicator, light blue in color, changes to violet or purple (very light violet to deep purple) | |
| 19094550 | How does Lugol's Iodine work and what does it test for? What does a positive result look like? | mix with test food. test for starch, yellow or light brown in color, positive it turns dark purple or even black | |
| 19094551 | How does Sudan III work and what does it test for? What does a positive result look like? | mix with test food. test for lipids, changes to orange red | |
| 19109908 | Proteins are polymers. TF | True | |
| 19109909 | Glucose is a polysaccharide. TF | False | |
| 19109910 | Lugol's Iodine indicates the presence of sugar. TF | False | |
| 19109911 | There are 20 different amino acids. TF | True | |
| 19109912 | Carbohydrates, lipids, and proteins are good sources of energy. TF | False | |
| 19109913 | A monounsaturated fat only has one double bond. TF | True | |
| 19109914 | Saturated fats are liquid at room temperature. TF | False | |
| 19109915 | Hydrolysis is the chemical reaction that helps build up polymers. | False | |
| 19109916 | Since water is a polar molecule, why do lipids not dissolve in water? | Lipids are nonpolar. |
