The diversity of functional groups on sugars that can form glycosidicbonds greatly increases the information content of glycans relative to oligopeptides. Consider three amino acids, A, B, and C. How many tripeptides can be formed from one molecule of each amino acid? Now considerthree sugars—glucose, glucuronic acid, and N-acetylglucosamine. Use shorthand (e.g., Glcα(1 → 4)GlcUAβ(1 → 4)GlcNAc to represent 10 trisaccharides with the sequence Glc-GlcUA-GluNAc. Is your list exhaustive?

Cysteine proteases are enzymes that degrade proteins. You may have heard of some examples of these types of proteins before! Bromelain is an enzyme found in pineapple that is commonly used as a meat tenderizer and is the reason Jell-O with fresh pineapple will not solidify. Cysteine proteases are remarkably similar to serine proteases (like chymotrypsin), except they have a cysteine in their active site rather than a serine. Using the mechanism that we discussed for serine proteases, draw a corresponding mechanism for a cysteine protease cleaving the bond between an alanine-glycine dipeptide. Note that cysteine proteases do not require an aspartate in their active site. Also note that the cysteine is usually in its thiolate form (deprotonated) and the histidine is in its imidazolium form (fully protonated) in the resting state of the enzyme.
The human body uses the branched polymer glycogen for short term storage of glucose in the liver. It is broken down by the stepwise removal of the terminal glucose monomer. Explain why it is an advantage for glycogen to have a branch chain structure rather than a linear structure. (A pargraph would be great)
