The diagams shows a ring structure of glucose. Which form of glucose is shown and in which molecule is it present?
Correct answer: B. Starch
- A. Cellulose
- B. Starch
- C. Glycogen
- D. Chitin
Explanation
Option B is correct. The given diagram shows an α-glucose ring structure, identifiable by the downward orientation of the hydroxyl (OH) group on the first carbon. Starch is a polysaccharide composed of numerous α-glucose units linked together. Option A is incorrect because cellulose consists of β-glucose, Option C is incorrect in this specific context as it refers to glycogen which is not the focus here, and Option D is incorrect because chitin is not made from glucose.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
