Concept explainers
(a)
Interpretation: Heparin has to be classified as a storage polysaccharide, a structural polysaccharide, an acidic polysaccharide or a non-polysaccharide.
Concept introduction: The polysaccharide that is a storage form for monosaccharides and is used as an energy source in cells is called as storage polysaccharide. The polysaccharide that provides the structural elements for the animal exoskeletons and plant cell walls is called structural polysaccharide. The polysaccharide that has disaccharide as the repeating unit, one of the disaccharide component is an amino sugar and one or both the disaccharide component have a negative charge due to carboxyl group or sulphate group.
(b)
Interpretation: Chitin has to be classified as a storage polysaccharide, a structural polysaccharide, an acidic polysaccharide or a non-polysaccharide.
Concept introduction: The polysaccharide that is a storage form for monosaccharides and is used as an energy source in cells is called as storage polysaccharide.

- These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ? H Harrow_forwardQ5: Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Clearly show stereochemistry by drawing the wedge-and-dashed bonds.
