Question

What is the basic formula for starch?

• A. $(C_{6}H_{12}O_{ 6})_{n}$
• B. $(C_{6}H_{10}O_{5})_{n}$
• C. $C_{12}H_{22}O_{11}$
• D. $(C_{6}H_{12}O_{4})_{n}$

Answer 1

Answer: (B)

$(C_{6}H_{10}O_{5})_{n}$

Answer 2

Starch is a polysaccharide comprising glucose monomers joined in $\alpha-1,4$ linkages. The basic chemical formula of the starch molecule is $\left( C _{6} H _{10} O _{5}\right)_{ n }$.
