Is lactose a reducing sugar? To answer this, first draw lactose, then label the anomeric carbons on each monomer and determine if lactose is a reducing/non-reducing sugar.

b) Is Sucrose a reducing sugar? Answer this similar to the question above however (no need to draw structures like above)

Expert Solution

Reducing sugars are those which can act as a reducing agent. Inorder to be a reducing agent, the sugars need a free anomeric carbon (C-1) carbon i.e., the carobon present in the carbonyl form (either in ketone or aldehyge group of the sugar). All monosaccharides are reducing sugars because they have a free anomeric carbon. They can exist in hemiacetal form and also in free acetal form.

When it comes to disaccharides, the sugars can be either reducing or non non reducing according to the glycosidic bond they are linked in.

Even though sucrose is considered a non-reducing sugar, it may have acted as a reducing sugar with certain reagents. Suggest a reason for this observation.

Why is sucrose not concidered a reducing sugar?

Answer A- H please a) Draw a Supply Curve and the Demand Curve for the Sugar Label the supply S1 and the demand D1. Label on the vertical axis P for the equilibrium price and label the horizontal axis Q for the equilibrium quantity. We currently have the sugar market in equilibrium at a price of $3 per pound and 100,000 pounds. Now assume that the state government just announced a new price floor program for the sale of sugar....

First, draw out the pedigree. Label everyone as affected/unaffected. Write in each genotype you KNOW for sure from the information you are given in the problem. Then use Mendelian genetics & statistical rules to figure out the chance the unaffected people are carriers. Note: in order to figure out the probability that a couple will have an affected child, you must first determine the probability that each parent is a carrier of the mutant gene in question. Then you must...
