the difference between amylose and amylopectin is
Hi
As per your question Starch may be a colourless and odourless polysaccharide that's found in plants as
stored carbohydrates. it's a polymer of glucose monomers that are linked with one another to make
polysaccharide.
Starch consists of two sorts of polysaccharide molecules:
Amylose
Amylopectin
Amylose and Amylopectin
Amylose may be a polysaccharide made from several D-glucose units. they're linked by 1,4-glycosidic
bonds. When iodine is added to starch, the color changes to navy or black thanks to the presence of
amylose present within the starch. Amylose is soluble in water and may be hydrolyzed into glucose units
by the enzymes α- amylase and β-amylase.
Amylopectin may be a polymer of several D-glucose molecules. 80% of amylopectin is present in starch.
Amylopectin molecules are linked by α-1,4-glycosidic bonds and α-1,6-glycosidic bonds. When iodine is
added to starch, it gives reddish-brown appearance thanks to the presence of amylopectin. It readily
dissolves in predicament . On cooling, it forms a starch paste or starch gel.
Let us discuss the difference between amylose and amylopectin.
Following are the important difference between amylose and amylopectin:
Amylose Amylopectin
It is a straight-chain polymer of D-glucose units it's a branched-chain polymer of D-glucose units
Constitutes 20% of starch Constitutes 80% of starch
Solubility in water is less More soluble in water
Straight chain structure Branched structure
Amylose stains blue with iodine Amylopectin stains reddish-brown with iodine
Soluble in predicament without swelling Soluble in predicament with swelling
Does not form a gel when predicament is added thereto Forms a gel when predicament is added to it
Hope helpful.
Hello,
Amylose is a polysaccharide made of several D- glucose units linked with 1,4 glycosidic bonds. When iodine is added to starch it changes its colour to dark blue or black due to the presence of Amylose. Amylose is soluble in water and can be hydrolyzed into glucose units.
Amylopectin is a polymer of several D-glucose molecules. 80% of Amylopectin is present in starch. They are linker by alpha-1,4 glycosidic bonds and alpha-1,6 glycosidic bonds. When iodine is added to the starch the colour changes to reddish brown due to the presence of Amylopectin ,
