Q33 / 160 · AP EAMCET 2024 (22 May Shift 2) · Chemistry

Which of the following is correct statement?

A
Starch is a polymer of $\beta$-D-glucose
Correct answer
B
Amylose is a component of starch
C
Proteins are biopolymers of only one type of amino acids
D
Lactose is a disaccharide of $\alpha$-D-glucose and $\beta$-D-glucose

Solution

Starch is a polymer of $\alpha$-glucose. Amylose and Amylopectin are component of starch. Lactose is composed of $\beta$-D- galactose and $\beta$-D-glucose. Proteins are composed of many type of amino acid.

Hence, the correct answer is option: 'B'.
