| 8615172524 | C₆H₁₂O₆ | What is the chemical formula for all of these monosacharides? | | 7 |
| 8615172525 | Their arrangement is different. They are isomers, meaning their chemical formula is the same but their arrangement is different. | How are these three monosaccharides different from each other? | | 8 |
| 8615172526 | lactose, sucrose, maltose | What are the three disaccharides? | | 9 |
| 8615172527 | They are different depending on which monosaccharides are bonded with each other. Glucose and glucose make maltose, glucose and fructose make sucrose, and glucose and galactose make lactose | How are these three disaccharides structurally different from each other? |  | 10 |

| 8615172529 | They're isomers. They have the same chemical formula but different chemical arrangements. So, they contain the same molecules, but look different. | How are starch and cellulose structurally different from each other if they're both made up of the same monosaccharide? | | 12 |
| 8615172530 | The human body breaks own starch and disaccharides because they are carbohydrates. The body needs carbohydrates because they are sugars, and the body gets energy from sugar. | Why does the human body break down (digest) starch and disaccharides? (What does the body need, and why?) | | 13 |
| 8615172531 | The human body uses enzymes, like amylase, to break them down into monosaccharides so they can be used in the body as a source of energy. | How does the human body break down starch and disaccharides? | | 14 |
| 8615172532 | The human body can break down starch because it has the enzyme, amylase, to break it down. The human body does not have the enzyme, cellulase, that is used to break down and digest cellulose. | Why can the human break down starch and not cellulose? | | 15 |
| 8615172533 | Some people stop producing the enzyme lactase, which breaks down lactose. Therefore, making it difficult to digest lactose. | Why do some people become lactose intolerant later in life? | | 16 |

| 8615172540 | Chitin | Which polysaccharide is found in the exoskeletons of crustaceans? | | 23 |
| 8615172541 | Glycogen | Which polysaccharide is the storage form of glucose in plants? | | 24 |
| 8615172542 | Glycogen | Which polysaccharide is the storage form of glucose in plants? | | 25 |
| 8615172543 | It is when two molecules are bonded together by taking away water. | What is synthesis by dehydration? Also known as dehydration synthesis? | | 26 |
| 8615172544 | No, because you only use dehydration synthesis to create disaccharides and polysaccharides, but fructose is a monosaccharide. | Could synthesis of dehydration be used to form fructose? | | 27 |
| 8615172545 | Yes, because starch is the polysaccharide. And in order to get a polsysaccharide you have to bond three glucose molecules together | Could synthesis by dehydration be used to form starch? | | 28 |
| 8615172546 | Enzyme | What is a protein macromolecule called? | | 29 |
| 8615172547 | Monopeptide, dipeptide, polypeptides | A protein molecule is a long strand of what type of smaller molecule? | | 30 |
| 8615172548 | 20 | How many different amino acids are there? | | 31 |
| 8615172549 | Dipeptide | If only two amino acids are bonded together, what do you have? | | 32 |

| 8615172551 | Peptide bond | What type of bonds hold to amino acids together? | | 34 |
| 8615172552 | We need polypeptides and peptides because they give us the enzymes we need to break down polysaccharides into monosaccharides which we convert into energy | Why does the human body breakdown polypeptides and peptides? (What does the body need, and why?) | | 35 |
| 8615172553 | Yes, we put amino acids together to create polypeptides which help us break down polysaccharides | Does the human body ever put amino acids together to make polypeptides? If it does, what is the purpose? | | 36 |
| 8615172554 | Yes | Does the body use synthesis by dehydration to bond amino acids together to make peptides and polypeptides? | | 37 |

| 8615172557 | Glycerol and fatty acids | A fat molecule is made out of what smaller molecules? | | 40 |
| 8615172558 | One glycerol and three fatty acids | How many of each type of glycerol and fatty acid molecules are needed to make one fat molecule? | | 41 |
| 8615172559 | Yes | Are all glycerol molecules the same? | | 42 |
| 8615172560 | No; the different types are butyric, lauric, and caproic | Are all fatty acid molecules the same? | | 43 |
| 8615172561 | Unsaturated fats are liquid at room temperature and contain double bonds, or kinks. These are healthier for your body because they are easier to break down and separate. They're also healthier because they raise HDL levels (good cholesterol). Saturated fats are solid at room temperature. They do not contain double bonds or kinks and have a much more tightly packed structure, making it more difficult to break down. They raise LDL levels (bad cholesterol), and are more likely to clog arteries. | What's the difference between saturated and unsaturated fats? | | 44 |
| 8615172562 | Monounsaturated fat molecules only have one double bond, wheres polyunsaturated fats have multiple double bonds. | What is the difference between polyunsaturated and monounsaturated fat molecules? | | 45 |
| 8615172563 | Saturated fats are worse for the body because they raise levels of bad cholesterol (LDL) and lower levels of good cholesterol (HDL). They are also more likely to clog your arteries. | Which are worse for you: unsaturated or saturated fats? | | 46 |
| 8615172564 | butter, fatty beef, cheese, cream | What types of foods contain saturated fats? | | 47 |
| 8615172565 | sunflower seeds, nuts, fish, canola oil, | What types of foods contain unsaturated fats? | | 48 |
| 8615172566 | Saturated fat | Which type of fat tends to be solid at room temperature? | | 49 |
| 8615172567 | Triglycerides are a way to store energy for the human body | Why does the body need to break down triglycerides? | | 50 |

| 8615172569 | Yes, this is used to store fat. Glycerol and fatty acid molecules form to create lipids. | Does the human body ever put glycerol and fatty acid molecules to form a macromolecule? If it does, for what purpose? | | 52 |
| 8615172570 | Yes | Does the human body use synthesis by dehydration to bond glycerol and fatty acid molecules to form a lipid? | | 53 |
