Question

A linear polymeric biomolecule with reducing and non-reducing ends is
A)RNA
B)DNA
C)Amylose
D)Protein

Answer 1

Hint: Carbohydrates are commonly sweet in flavor and hence cited as sugars. Carbohydrates are characterized as optically effective polyhydroxy aldehydes or ketones or the mixtures which generate components of such species on hydrolysis.

Complete answer:
Before we discuss the correct option, let us know a little more about reducing and non-reducing sugars.
Reducing sugars are sugars where the anomeric carbon possesses an OH group connected that can lessen other solvents. Non-reducing sugars do not possess an OH group connected to the anomeric carbon so they cannot lessen other mixtures.

Option C: Reducing sugars are the sugars which retain an available OH group. Starch is constructed by a-1,4 associations among two glucose components which are broken down during its absorption. It occurs in two shapes understood as amylose and amylopectin. Amylose is a linear poly-D-glucose in which the monosaccharides are pertained by alpha 1, 4 connections. One edge of the amylose has an available OH group so it is understood as a lessening end while the OH group on the other edge shapes the glycosidic bond so it is realized as the non-reducing end. This is the correct option.

Hence, the correct answer is option (C)

Note: Carbohydrates are also called sugars in common, some partly methylated sugars and amino sugars and amino sugars commonly and one natural nitro sugar is recollected. All carbohydrates are polyhydroxy aldehydes or ketones or materials that generate these on hydrolysis. They are primarily categorized into two species, they are reducing sugars and non-reducing sugars.
