Question
Carbohydrate reading assignment. This takes the place of the carbohydrate coverage in the lecture outlines. Consult Becker's World of the Cell. You may also benefit from consulting Campbell& Reece, now called Campbell Biology, which is the freshman text. Be sure to look at all figures and read their legends. What three elements make up the bulk of carbohydrate compounds? If a carbohydrate has more than those three elements, what element m What functional group is especially common in carbohydrates? Carbon ght it be? N Because of this functional group, all carbohydrates fall into what class of compounds? Hint: nearly all compounds that contain that function group are considered Sugars Recognize and understand the following: Monosaccharides. See slide 12 in Ch 02&03 extra slides.ppt. Aldoses (aldosugars) and ketoses (ketosugars) Trioses, pentoses, and hexoses Linear and ring forms Where do you find the disaccharide lactose? Where do sucrose?-0-f Be able to draw condensation/dehydration to link carbohydrates and hydrolysis to separate them. beat Understand the difference between and glycosidic linkages. Starch, glycogen, and cellulose. you find the disaccharide cane vr 6.p rozage keirnttn rugor Which organisms contain them? Within those organisms, where do you find them? How are they used (storage vs. structure)? which contains linkages and which contains ? Which can we digest in our guts? Which can't we? The suffix -ose implies carbohydrate. Don't confuse it with-ase. What does the suffix-ase imply?Explanation / Answer
3. Functioanl groups are Carbonyl and aldehyde group and hydroxyl group. In all the form hydroxyl group is present.
4. Monosaccharides
5. Monosaccharides - Has a only one molecule of simple sugar.
Disaccharides - It has 2 molecules linked with each other.
polysaccharides - It has greater than 20 monosaccharides linked together.
Oligosaccharides - Carbohydrates that yield two to ten monosaccharide units
6. Disaccharides lactose - Milk
Disaccharides sucrose - Plants
7. Alpha glucose forms a spiral structure - -OH [hydroxyl] group that points downwards, away from the ring.
Beta glucose however forms a straight chain
8. Starch - Plants, leaves, Storage, Alpha, Yes
Glycogen - Animals, skeletal muscles, Storage, Aplha, Yes
Cellulose - Plants, Stem, Storage, Beta, No
9. Enzyme name ends with ase
