|
amylose is branched, amylopectin is a chain
|
|
Amylopectin releases easily, amylose does not
|
|
Amylopectin loses shape, amylose holds shape of potato
|
|
amylose is chain, amylopectin is branched
|
Detailed explanation-1: -Amylose is linear with a 1 → 4 -linkage whereas Amylopectin is branched and has both 1 → 4 and 1 → 6 -linkages.
Detailed explanation-2: -Amylose is a linear polysaccharide in which glucose residues are linked solely by -1, 4 glycosidic bonds. In contrast, amylopectin is a branched molecule in which the branch points consist of -1, 6 glycosidic bonds while the linear portions of the branches are made up of -1, 4 bond as in amylose (Fig.
Detailed explanation-3: -Amylose is an unbranched linear molecule polymer composed of -1, 4-d-glucose units linked by -d-(1–4) linkages. This naturally occurring polysaccharide not only swells in water but is also resistant to pancreatic -amylase and can also be degraded by the colonic microflora enzymes (Basit, 2000).
Detailed explanation-4: -Amylose is a straight linear chain of glucose molecules linked by -l, 4 glycosidic linkages as shown in Fig. 2.19, in the same manner as in the disaccharide maltose.
