A Haworth structure is shown for glucosamine in the article.
Draw glucosamine in its most stable chair conformation. Draw glucosamine
as an open chain compound in a Fisher projection. Is the glucosamine shown as the alpha- or beta-anomer?
Using the parent chain numbering system for glucose, give a more specific
name for this amine derivative of glucose. Using Haworth formulas, draw a structure for chitosan,
polyglucosamine. The polymer contains beta-(1-4') glucosidic linkages. Modify the drawing above to produce chitin, poly N-acetylglucosamine.
By what reaction procedure could the chitin be deacylated
to form chitosan? What is the by-product of the reaction? By what reaction procedure could the chitin be depolymerized? |
