Which of the following statement is incorrect:

Correct option is D

Why option (d) is incorrect (Correct Answer):
· Amylose is the water-soluble fraction of starch.
· It consists of linear chains of α-D-glucose linked mainly by α-1,4 glycosidic bonds.
· Therefore, stating that amylose is water-insoluble is factually wrong.
➡️ Hence, option (d) is the incorrect statement, as given in the image.
❌ Why other options are correct
Option (a): Amylose is water soluble fraction of starch
· Correct.
· Amylose dissolves in hot water due to its linear structure.
Option (b): Amylopectin is water-insoluble fraction of starch
· Correct.
· Amylopectin has a highly branched structure (α-1,4 and α-1,6 linkages).
· This makes it less soluble in water.
Option (c): α-D glucose units are present in amylose and amylopectin
· Correct.
· Both starch components are polymers of α-D-glucose.
�� Key Points to Remember
· Starch is composed of amylose (linear, soluble) and amylopectin (branched, insoluble).
· Both contain α-D-glucose units.
