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.
