Glycogen's Polymer Formula

Steps:

• Glycogen is a branched polysaccharide made of glucose units linked by glycosidic bonds.
• Each glucose monomer (C₆H₁₂O₆) loses H₂O during polymerization, forming a repeating unit of C₆H₁₀O₅.
• The general formula represents the polymer as (repeating unit)_n, where n is the degree of polymerization.
• Confirm the formula matches standard biochemistry references for glycogen.

Why C is correct:

• (C₆H₁₀O₅)_n is the established formula for glycogen, reflecting the dehydrated glucose units in its α-1,4 and α-1,6 linkages.

Why the others are wrong:

• A uses incorrect subscript notation, implying a different hydration state.
• B omits the polymer indicator, suggesting a monomer.
• D includes an extra oxygen, altering the empirical ratio.

Final answer: C
