Question

Question:L-Sucrose tastes sweet, but it is not metabolized. It has been suggested as a potential nonnutritive sweetener. Draw the molecular structure of L-sucrose, using Figure 23.16b as a starting point.

Short answer

The molecular structure of L-sucrose is as follows:

Step-by-step solution

Composition of L-sucrose

L-sucrose comes under the class of carbohydrates.It has a sweet taste and not metabolized. It acts as a potential nonnutritive sweetener. It is the combination of alpha-L-glucopyranose and beta-L-fructofuranose.

Step 2: Molecular structure of L-sucrose

L-sucrose can be formed by the removal of water from alpha-L-glucopyranose and beta-L-fructofuranose. The molecular structure of L-sucrose is given below:
