1. what is the most common organic molecule: glucose
2. why is glucose such a common organic molecule: it is versatile in its use in plants
animals and microorganisms
3. how is the bulk of glucose created: photosynthesis which converts co2 h2o into cellulose
starch and plant products
4. What is the chemical formula of glucose: C6H12O6
5. what is the general structural pattern of carbohydrates: CnH2nOn
6. What is another way to write the carbohydrate atom ratio: Cn(H2O)n
7. Due to this pattern during early experiments, we call glucose a
________________, or a carbohydrate: hydrate of carbon
8. what are additional terms used to describe carbohydrates: sugar monosaccharide
oligosaccharide polysaccharide
9. What does the term sugar mean in general conversation: sucrose and table sugar
10. What does the term sugar mean in scientific conversation: any carbohydrate molecule
11. where is the word saccharide derived from: Greek word for sugar
12. what in a monosaccharide: simple sugar or monomeric sugar
, 13. What is an oligosaccharide: short chains of monosaccharides joined together 14. what is
a polysaccharide: consist of large numbers of monosaccharides joined together in long chains by
O-glycosidic bonds
15. What are the functions of carbohydrates in organisms: 1.) energy source
2.) intermediates in metabolic pathways
3.) important to structure
16. what is an example of carbohydrates used as intermediates in metabolism: pentose
phosphate pathway, carbohydrate intermediates enable cells to produce
NADPH, which is used to control oxygen radicals
17. what is an example of carbohydrates used for structure: cellulose that is the basis of
cornstalks
chitin which is the base of insect shells basis of RNA DNA
18. what is aldose: monosaccharides with aldehyde group
19. what is ketose: monosaccharides with ketone group
20. what is an example of an aldose: D-glyceraldehyde
21. what is an example of a ketose: dihydroxyacetone
22. monosaccharides found in nature typically have how many carbons: 3-8 carbons
23. what are the smallest thee carbon trioses: glyceraldehyde and dihydroxyacetone
24 what is a Fischer projection formula: 2D structures representing 3D carbohydrates
25. who is the Fischer projection formula names after: Emil Fischer
, 26. What does the D- in saccharides mean: D three dimensional structure as supposed to L
structure
27. What is a D structure: dextrorotary right handed
28. What is a L structure: levorotary
Left handed
29. why is glucose known as dextrose in nature: in nature it is always in D form 30. The
two configurations for glucose and all other monosaccharides are determined by the
orientation of the OH group on the ___________ carbon.: penultimate
31. What is the penultimate carbon?: second to last carbon
32. Why do only D structures exist in natural systems: the activation site of enzymes that
produce glucose yield D configuration
33. What is an epimer?: 2 sugars that differ only in the configuration around 1 carbon
34. what are an example of epimers: D-glucose and D-mannose
35. what is a furanose ring: a five-membered sugar ring containing an oxygen atom
36. What are pyranose rings?: 6 atom rings
37. how did the carbohydrate rings get the oxygen component: when the alcohol group
reacted with another carbon to form a ring
38. What is a Haworth projection?: a structural model for drawing cyclic monosaccharides
39. What is an anomeric carbon?: carbon at which the OH is up or down (reacting carbon)
