What is the carbohydrate polymer that contains a nitrogen group on each monosaccharife

Answer;

Chitin

Explanation;Chitin is a compound found in the cell walls of fungi and the exoskeletons of insects and some other arthropods; composed of chains of nitrogen-containing, modified glucose molecules. Chitin is different from other polymers of carbohydrates or polysaccharides such as cellulose because of the substitution that occurs on the glucose molecule. Instead of a hydroxyl group (OH), the glucose molecules in chitin have an amyl group attached that consists of carbon and nitrogen.
