Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?
daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

                monomer/glucose     glycosidic bond    branching

1.starch              α glucose          1-4 and 1-6               branch and unbranced

  amylose                                       1-4                          unbranched

  amylopectin                               1-4 and 1-6              branched

2. dextran          α glucose          1-6                           branched

3. cellulose        β glucose           1-4                          unbranched, linear        

4. glycogen       α glucose           1-4 and 1-6              branched (shorter

                                                                                     branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.

Igoryamba

Answer:

A. Repeats of "Alanine-Arginine"

B. Repeats of "Tyrosine-Isoleucine"

C. Repeats of Aspartic acid

Explanation:

A. The synthetic RNA with GC repeats would have repeats to two codons: GCG and CGC which in turn code for alanine and arginine amino acids respectively.  Hence, its polypeptide would have repeats of "Alanine-Arginine"

RNA: GCG CGC GCG CGC GCG CGC  

Alanine-Arginine-Alanine-Arginine-Alanine-Arginine-Alanine-Arginine ...

B. The synthetic RNA with UA repeats would have repeats to two codons: UAU and AUA which in turn code for tyrosine and Isoleucine amino acids respectively.  Hence, its polypeptide would have repeats of "Tyrosine-Isoleucine"

RNA: UAU AUA UAU AUA UAU AUA

Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine

C. The synthetic RNA with GAC repeats would code for polypeptide of aspartic acid only as GAC codes for aspartic acid.

RNA: GAC GAC GAC GAC GAC GAC

Aspartic acid-Aspartic acid-Aspartic acid-Aspartic acid-Aspartic acid-Aspartic acid
