  • question_answer
                Cellulose, the most important constituent of plant cell wall is made up of:               

    A)              branched chain of glucose molecules linked by , 1,6 glycosidic bond at the site of branching

    B)              unbranched chain of glucose molecules linked by , 1,4 glycosidic bond

    C)  branched chain of glucose molecules linked by , 1, 4 glycosidic bond in straight chain and , 1, 6 glycosidic bond at the site of branching

    D)              unbranched chain of glucose molecules linked by  \[\beta \], 1, 4 glycosidic bond

    Correct Answer: D

    Solution :

                    Cellulose \[{{({{C}_{6}}{{H}_{10}}{{O}_{5}})}_{n}}\] is the most abundant organic polymer. It is a polysaccharide an; consists of long unbranched chains of glucose residues linked by \[\beta \], 1-4 glycosidic bonds, In plants, cellulose is formed from sugar. It serves as building material in the formation of cell wall.
