Question

What are the 2 types of starch? Indicate whether they are branched or linear.

A) Amylose (Linear), Amylopectin (Branched)
B) Glucagon (Linear), Glycogen (Branched)
C) Fructose (Linear), Sucrose (Branched)
D) Maltose (Linear), Lactose (Branched)
Correct Option: A) Amylose (Linear), Amylopectin (Branched)

Answer 1

Starch is composed of two types of polysaccharides: amylose (linear) and amylopectin (branched).

A) Amylose (Linear), Amylopectin (Branched)

Step-by-step explanation:

Starch is composed of two types of polysaccharides called amylose (linear) and amylopectin (branched). Amylose consists of unbranched chains of glucose monomers connected by 1,4 glycosidic linkages. On the other hand, amylopectin is composed of branched chains of glucose monomers connected by both 1,4 and 1,6 glycosidic linkages.

For example, amylose is like a straight line of glucose molecules, while amylopectin has branches that extend from the main chain of glucose molecules.
