At branching of molecules of starch, which glycosidic bond occurs?
Correct answer: D. α-1,6
- A. γ-1,4
- B. β-1,6
- C. β-1,4
- D. α-1,6
Explanation
In the structure of starch, branching occurs via α-1,6 glycosidic bonds. Amylopectin, a component of starch, has a branched structure due to these α-1,6 linkages. The other options are incorrect because they refer to different types of glycosidic bonds that are not involved in the branching of starch. For example, β-1,4 bonds are typical of cellulose, and γ-1,4 bonds are not relevant to carbohydrates.

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.
