1. Which carbon in erythrose would tell you if the monosaccharide is D or L? Give the
carbon's number in your answer. ANS On carbon number 3, which is the penultimate
carbon.
2. Glucose and mannose are epimers. Name another epimer of glucose be- sides
mannose. ANS galactose

ANS No. This compound has does not fit the formula CnH2nOn as indicated in the module.
There is one additional oxygen in this compound.

  4. When is the ± 1’c6onnection typically found in carbohydrates? ANS The ± 1’ 6 bond is found in polysaccharides when branching occurs.
  1. What are the similarities and differences between amylose and amy- lopectin? Explain in at least three complete sentences. ANS Similarities Both of are homopolysaccharides of glucose. They each have ± 1 ’ 4 connections between glucose. They each are part of starch. Differences Amylopectin has branching with ± 1’ 6 linkages. Amylose does not. Amy- lopectin is typically larger than amylose.
  2. How is chitin different from cellulose? ANS Chitin has glucose with derivatives attached. -NH-CO-CH3 is connected to each glucose.
  3. Where are ± 1 ’ 6 bonds found in carbohydrates? ANS They are found where glycogen and amylopectin branch.
  4. In what ways are amylose and a protein alike? ANS They both can form alpha helices.
  1. long chains of 20 or more monosaccharides joined together. ANS Polysaccha-rides
  2. functions of carbohydrates ANS -used as an energy source in most organisms, whether the organism synthesizes the carbohydrate or acquires it from food sources -carbohydrates serve as intermediates in metabolic pathways.

-carbohydrates play an important role in structure. -carbohydrates serve a structural role in RNA and DNA.

  1. two-dimensional structures that represent three-dimensional carbohy-drates or other organic molecules ANS Fischer projection
  2. differences and similarites between "D and L" ANS These two molecules pos-sess nearly all of the same physical and chemical properties but differ in the three-dimensional arrangement.
  3. second to last carbon ANS penultimate
  4. why is glucose known as dextrose ANS because glucose in nature is always the D form.
  5. why does only the D molecule exists in natural systems ANS -it is due to the
  1. example of a molecule that contains two different monosaccharides, galac-tose and glucose, joined together by a ² 1’4connection ANS lactose
  2. consist of large numbers of monosaccharides joined together in longchains by O-glycosidic bonds ANS Polysaccharides
  3. Glucose makes up three crucial homopolysaccharides ANS starch, glycogen,and cellulose
  4. plants store carbohydrates in the form of ANS starch
  5. what is starch made up of ANS amylose and amylopectin
  6. is a linear chain of glucose joined together in ± 1 ’ b4onds in one continuous chain with no branching. ANS amylose

37. has a long chain of glucose bonded together, but it also has branches every 24 to 30 glucose molecules apart on the main chain and these branchesthen have large numbers of glucose residues connected by ± 1 ’ c4onnections.- ANS amylopectin

  1. what do branch points permit amylocpectin to do ANS form larger compounds
  2. animal form of carbohydrate storage. ANS glucose
  3. how do carbohydrates typically join together? ANS o-glysidic linkeage
  4. with what kind of linkeages can make very long chains ANS alpha 1-->
  5. how is lactose formed ANS galactose and glucose beta 1-4 connection
  6. how is sucrose formed ANS fructose and glucose
  7. when branching occurs what kind of linkage is formed ANS 1-
  8. single type of monosaccharide, such as glucose ANS homopolymer
  9. have two more types of monosaccharides, often in repeating fashion, inthe structure. ANS Heteropolysaccharides
  10. linear chain of glucose joined together in ± 1 ’ 4 bonds in one continuous chain with no branching. ANS amylose
  11. has a long chain of glucose bonded together, but it also has branchesevery 24

stabilize structure

  1. long chains of monosaccharides put together into polysaccharides ANS carbo- hydrates
