Most of the monosaccharides form a ring structure when in solution. For example, ribose will create a five cornered ring known as:
Correct answer: B. Ribofuranose
- A. Glucopyranose
- B. Ribofuranose
- C. Glyceraldehyde
- D. Acetaldehyde
Explanation
When most monosaccharides are in a solution, they tend to form ring structures. Ribose, for example, forms a five-membered ring, which is known as RibofuranoseThe five-membered ring structure of ribose is called ribofuranose. In contrast, a six-membered ring is referred to as glucopyranose (Option A). Glyceraldehyde (Option C) and acetaldehyde (Option D) are not related to the ring structures of ribose or other common monosaccharides.

About Carbohydrates
Carbohydrates are organic compounds classified as monosaccharides, disaccharides and polysaccharides according to their structure and hydrolysis products. The topic covers glycosidic bonds, glucose and fructose, sucrose, lactose and maltose, starch, glycogen and cellulose, along with their roles in energy storage, structural support and food tests.
