Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Carbohydrate monomers are typically molecules of what shape?
A
capital E
B
chains
C
rings
D
None of the above
Explanation: 

Detailed explanation-1: -Monosaccharides can exist as a linear chain or as ring-shaped molecules; in aqueous solutions they are usually found in ring forms.

Detailed explanation-2: -In carbohydrates, a five-membered ring with an oxygen in it is called a furanose (another common form, a six-membered ring, is called a pyranose). There are two diastereomers formed. they are sometimes called anomers. That means they differ in 3D space at the anomeric center; the anomeric center is the C=O.

Detailed explanation-3: -A carbohydrate with three carbons is a triose, a carbohydrate with four carbons is a tetrose, and a carbohydrate with five or six carbons is known as a pentose and a hexose respectively. These monomers exist as a ring structure, which makes them more stable.

Detailed explanation-4: -Linear versus ring form of the carbohydrates Monosaccharides can exist as a linear chain or as ring-shaped molecules; in aqueous solutions, they are usually found in ring forms (Figure 3).
