Question

Notes: 1. If you methylate a carbohydrate, you form methoxy groups on the free OH groups. These methoxy groups are resistant to hydrolysis in 2 M $H_2SO_4$. This experimental scenario allows you to figure out the free hydroxyls in a di-, oligo- or polysaccharide. 2. When a polymer is formed, new bonds form between monomeric units via a dehydration reaction. Water has a MW of 18 g/mol. Monomeric Glucose has a MW of 180 g/mol. Problems: 1. What is the average MW of each Glucose unit in a Glucose polysaccharide?

          Notes:
1. If you methylate a carbohydrate, you form methoxy groups on the free OH groups.
These methoxy groups are resistant to hydrolysis in 2 M $H_2SO_4$. This experimental
scenario allows you to figure out the free hydroxyls in a di-, oligo- or polysaccharide.
2. When a polymer is formed, new bonds form between monomeric units via a
