Carbs and Lipids
Questions + Answers
| Question | Answer |
|---|---|
| This element can form 4 bonds and is the main element of organic compounds. | Carbon |
| Why are lipids and efficient form of energy storage? (HINT: Think about the bonds for this one.) | They are long chains of hydrogen and carbon |
| The characteristic that ALL lipids have in common is- | Does not disolve in water. (I.E. Is not soluble in water) |
| Lipids are made of- | C,H,O, |
| Lipids differ from most other larger biomolecules in that they- | Are hydrophobic |
| Single parts/units of a biomolecule are called: | Monomers |
| What elements make up carbohydrates? | Carbon, Hydrogen, Oxygen |
| An example of an unsaturated fat would be? | Vegetable Oil |
| The 3 types of carbohydrates are- | Monosaccharide, disaccharide, polysaccharide |
| What is the name of the reaction that involves the removal of a single water molecule from between two monomers? | Dehydration Synthesis |
| All carbohydrates names end with- | -ose |
| What is an unsaturated fat? | Contains one or more double or triple bonds, come from plants, have fewer hydrogen atoms, curves (diagram), 2 types: Monounsaturated and Polyunsaturated |
| What is a saturated fat? | Contains no double bonds, has the perfect amount hydrogen atoms, also in a straight line (diagram) |
| What is most important thing about lipids? | They store energy. They also have waterproof barriers, are chemical messengers and are used for insulation. |
| The ratio of carbon to hydrogen is: | 1:2 |
| What are the most common functional groups that lipids are composed of? | Glycerol (and alcohol with 3 oxygen groups) and Fatty Acids (long Hydrocarbon chains) |
| What are Hydrocarbon chains? | Chains made of hydrogen and carbon linked together |
| What kind of molecules are lipids if they can't bond to water? | Nonpolar |
| Are lipids mostly solid or mostly liquid at room temperature? | They tend to mostly be solid (Ex. Animal fat, Lard and Butter) |
| What is the Valance of Carbon? | Carbon has a valance of 4 |
| Are unsaturated fats mostly solid or mostly liquid at room temperature? | They tend to mostly be Liquids (Ex. Oils and Margarine) |
| Why is Carbon extremely veritable? | It can bond with itself up to 3 times |
| What is a double bond? | It is when you have a lone electron that bonds with an adjacent carbon |
| What is a Phospholipid? | It is a major component of cell membranes; it contains a hydrophilic end and 2 hydrophobic tails. |
| What is a Triglyceride? | It is a glycerol molecule (CH2) with 3 fatty acid chains (1 glycerol attached to 3 fatty acid chains) |
| What are steroids? | They are lipids with 4 rings bonded together, They are vital as hormones (which send chemical signals which are used in the body |
| What is cholesterol? | Cholesterol is a key bonding agent which keep that nerve endings from breaking. |
| How do you identify something that is polyunsaturated? | Look for more than 1 double bond |
| How do you identify something that is monounsaturated? | Look for ONLY 1 double bond |
| Why does oil stain clothes? | All the oil gets trapped between the fibers of the clothes |
| How can you figure out if something is a lipid or not? | You can figure out if something is lipid or not with brown paper. |
| What are both Lipids and Carbohydrates classified as? | Biomolecules |
| What are carbs used for? | Carbs are used for energy and structural support |
| What happens if carbs are not used for energy? | They are stored as fat which is glycogen(a Polysaccharide) |
| What does the root word sacchar mean? | sugar |
| What is lactose? | A disaccharide |
| What is the ratio of carbs? (Carbon:Hydrogen:Oxygen) | 1:2:1 (Ex. C6 H12 O6) |
| What are monomers called? | Monosaccharides |
| What are dimers called? | Disaccharides |
| What are Polymers called? | Polysaccharides |
| What do Carbohydrates occur in? | Rings |
| What do plants create the most of? | Carbohydrates |
| What is used as a common source for energy for most organisms? | Glucose |
| What are other types of carbs in nature? | Fructose (Fruit Sugar), Lactose(Milk Sugar), Sucrose(Table Sugar), Ribose/Deoxyribose (Important for DNA and RNA) |
| What do carbohydrates use to bond to each other? | Dehydration Synthesis |
| What is a Glucosidic bond? | What its called when 2 carbohydrates are joined to each other |
| What is the cellular form of glucose? | Cellulose |
| Where is Glycogen stored? | The liver |
| What are Starches? | Long chains of carbs in plants |
| What do plants use for structural support? | Cellulose (Polysaccharide) |
| What are unsaturated fats missing? | A hydrogen ring |
| How many double bonds does a monounsaturated fat have? | 1 Double bond |
