Question

Which is the basic molecule in starch?

Answer 1

Dear Student,

◆ Answer -

Basic molecule in starch is D-glucose.

● Starch -

• It is produced by most green plants as energy storage.
• It's carbohydrate polymer formed several D-glucose units in α-1,4-glycisidic linkage.

Starch polymer is made of two imp structures -

1. Amylose -

• It is unbranched polysaccharide
• Amylose is 20% of starch
• It's straight polymer with alpha-1-4 glycosidic linkage

2. Amylopectin -

• It is branched polysaccharide
• Amylopectin is 80% in starch
• It's branched polymer with alpha-1-4 & alpha-1-6 glycosidic linkage

Thanks for asking..

Answer 2

The basic molecule in starch is Glucose.

Explanation:

• Food is stored in the plants and animals in the form of complex compound which is known as Starch.

• Starch is a "white granular organic compound" which is formed in green plants. Its chemical formula is $(C_{6}H_{10}O_{5})_n$.

• Starch is a polysaccharide made up of glucose monomers joined at α-1,4 linkages.

• Multiple glucose monomers are linked together to form a complex polysaccharide, which in turn combine to form the molecule of starch. Thus, building unit of Starch is Glucose.
