Question

A. What's the differance between Amylose and Amylopectine? (please highlight the important differances)

B. What's the differances between Glycogen and Amylan? (also where is it stored?)

C. In which configuration we will find Glucose in Cellulose? (not even sure I got what they meant by configuration? do they mean like in orgo cys trans/equatorial and axial/ or just alpha beta glucose???)

thanks in advance!

Answer 1

The answer to the above questions

A)

S.NO	Amylose	Amylopectin
1	It constitutes about 20% of the starch	It constitutes about 80% of the starch
2	It is a straight chain polymer of D-glucose units	It is a branched chain polymer of D-glucose unit
3	More soluble in water	Less soluble in water
4	With Iodine stains blue	With Iodine stains reddish brown

B)  Amylan?????

There is nothing called amylan, might be a typo. Please repost the question correctly.

C) Cellulose is a linear polysaccharide polymer which has many glucose monosaccharide units. It consists of long polymer chains of glucose units connected by a beta acetal linkage. All the monomer units are beta-D-glucose, and all the beta acetal links connect to C # 1 of one glucose to C # 4 of the next glucose. That is the configuration of glucose in cellulose.
