Answer #1

Galactose is monosaccharide sugar. It is composed of Carbon, Hydrogen and Oxygen atoms. It is an aldohexose sugar : as it has 6 carbon atoms and an aldehyde group. It is less sweeter and stable than glucose. Although the molecular formula is same as Glucose i.e. C6H12O6. The positioning of the -OH group at the 4th carbon atom is different. Galactose can exist either as 1. Open chain form or 2. Cyclic form.

Structure of Galactose:

1. Open chain form.

2. Cyclic form.

L-galactose can be prepared from D-galactose by a route that begins with oxidation to D-galactaric acid, which cyclizes to form two six-membered-ring lactones. After separating the lactones and reducing them with sodium amalgam, one lactone returns D-galactose while the other one yields L-galactose. Draw the structure of the lactone that yields L-galactose. - Use the wedge/hash bond tools to indicate stereochemistry. - You do not have to explicitly draw H atoms. - If a group is achiral, do not use...

A passive transporter is discovered that can transport both galactose and glucose. The pore of the transporter can accommodate a single sugar at a time. If the extracellular concentrations of galactose and glucose are 0.25 and 4.0 mM, respectively, and the intracellular concentrations are 0.4 and 3.0 mM, respectively, which sugar is most likely to enter the cell through the transporter? Provide two reasons for your answer.
