Chapter 5, Problem 13PIAT
Summary Introduction
To review:
The structural difference between fructose and glucose accounting for the fact that fructose tastes more sweeter.
Introduction:
The sweetness of a substance is based on its ability to interact with the proteins present on the tongue’s taste receptors or buds and form hydrogen bonds with them. The sugars like fructose and glucose are sweet in taste because the hydroxyl groups in them can form the hydrogen bond with the proteins on the tongue’s taste buds.

What is/are the specific difference(s) between glucose and fructose?
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?
Many people who are lactose intolerant can eat yogurt, which is prepared from milk curdled by bacteria, without any digestive problems. Give a reason why this is possible. (Hint: Read the label on each of several yogurt containers. Do the ingredients make a difference?)
