Answer:
This question is incomplete
Explanation:
This question is incomplete, however the question seeks to test the students ability to identify a dextran. The question already gives a brief description of a dextran hence the attachment provides a visual representation of what has been described in the question.
Dextrans are polysaccharides made up of individual glucose units (monomers) that are joined together by α(1 → 6) glycosidic bonds (as seen in the second diagram of the attachment); i.e the C-1 (illustrated as α-1 in the attachment) of one glucose unit is linked to the C-6 (illustrated as α-6 in the attachment) of another glucose unit by glycosidic bond. These dextran polymers are also characterized by branches from α(1 → 3) [as seen in the second diagram of the attachment]; i.e the C-1 (illustrated as α-1 in the attachment) of the branch glucose molecule is attached to the C-3 (illustrated as α-3 in the attachment) of a glucose unit in the polymer chain of the dextran.
