Question

1. what does a monosaccharide look like? 11. what is a disaccharide? 12. how does a polysaccharide differ from a disaccharide? there are three classes of carbohydrate polysaccharides. the first is starch. starch is a carbohydrate used in food storage in plants. potatoes, pasta and rice are rich in starch. starches are very valuable because they provide a quick form of energy for the body. the second is glycogen. glycogen is used for food storage in animals. the third is cellulose. cellulose is used for structural support in plants (stems, leaves). 13. what are the three classes of carbohydrates? 14. which involves food storage in plants? 15. which involves food storage in animals? lipids lipids are the second class of organic macromolecules which includes fats and oils, and has the function of long - term energy storage in the body. the building block of lipids is the fatty acid, which is a chain of carbons with hydrogen attached. saturated fats have two hydrogens attached to each carbon (except the one at the end). saturated fats are unhealthy and include butter and crisco. unsaturated fats are missing at least one hydrogen and are kinked in shape. the unsaturated fats are oils. 16. what is the building block of lipids? 17. name examples of lipids. 18. describe the structure of a fatty acid.

Explanation:

1. A monosaccharide is a simple sugar with a general formula of (CH₂O)ₙ and can have linear or ring - shaped structures.
2. A disaccharide is a sugar formed by the condensation of two monosaccharides.
3. A polysaccharide is a long - chain polymer of monosaccharides, while a disaccharide is made of only two monosaccharides.
4. The three classes are starch, glycogen, and cellulose.
5. Starch is used for food storage in plants.
6. Glycogen is used for food storage in animals.
7. The building block of lipids is the fatty acid.
8. Examples of lipids include fats and oils.
9. A fatty acid is a chain of carbons with hydrogen attached, and may be saturated or unsaturated.

Answer:

1. Simple sugar with (CH₂O)ₙ formula, linear or ring - shaped.
2. Sugar formed by two monosaccharides condensation.
3. Polysaccharide is long - chain of monosaccharides, disaccharide has two.
4. Starch, glycogen, cellulose.
5. Starch.
6. Glycogen.
7. Fatty acid.
8. Fats, oils.
9. Chain of carbons with hydrogen, saturated or unsaturated.
