Question

Which examples of carbohydrates exhibit \(\alpha\)-link (\(\alpha\)-glycosidic link) in their structure?

• A. Amylose and Amylopectin
• B. Cellulose and Glycogen
• C. Glucose and Fructose
• D. Maltose and Lactose

Hint:

The \(\alpha\)-link in carbohydrates is a crucial bond in polysaccharides like starch. Recognizing these bonds helps in distinguishing between polysaccharides like amylose, amylopectin, and cellulose.

Answer 1

The Correct Option is A

The \(\alpha\)-link (\(\alpha\)-glycosidic link) in carbohydrates refers to the specific linkage between the monomer units of glucose in starch, which is found in amylose and amylopectin. Both amylose and amylopectin, which are components of starch, exhibit \(\alpha\)-glycosidic bonds. - Amylose is a linear polysaccharide with \(\alpha\)-1,4-glycosidic bonds between glucose units. - Amylopectin, which is a branched polysaccharide, has both \(\alpha\)-1,4-glycosidic bonds and \(\alpha\)-1,6-glycosidic bonds. Thus, the correct examples are amylose and amylopectin. Thus, the correct answer is: \[ \text{(1) } \text{Amylose and Amylopectin} \]
