Which statement best explains how the structure of a starch molecule relates to its function?

Q: Which best describes a starch molecule?

The basic chemical formula of the starch molecule is (C6H10O5)n. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form.

How the structure of a starch molecule relates to its function?

The chain coils in a spiral shape, held together by hydrogen bonds. This shape makes starch well suited to energy storage as it is compact, so takes up little space in the cell, and not very soluble in water, so does not affect the water potential of the cell.

Which best describes a starch molecule?

The basic chemical formula of the starch molecule is (C₆H₁₀O₅)_n. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form.

Starch and cellulose are two types of polysaccharides that are found in plants. However, they have different structures and functions. Starch is primarily used for energy storage, whereas cellulose is used for structure and support.

What are the structures of starch?

Starch molecules exist in two structural forms: amylose and amylopectin molecules. Amylose is starch that exists as glucose molecules bonded together in a linear chain or helical shape (i.e., a corkscrew or spiral staircase shape). Amylose makes up ~20-30% of the starch found in plants.
