What is the function of a control in reducing sugar experiment?

The function of a control in any experiment is to give you something to test your results against. If you were to test for reducing sugars by using Benedict's test, not having negative or positive controls, that is tests where you know which is negative and which is positive, then you wouldn't have accurate results to compare to.

Why cant table sugar be the positive control in test using Benedict's solution?
Table sugar, or sucrose, doesn't have an aldehyde group. Benedict's solution is used to determine if a reducing sugar is present. If it is a reducing sugar, the mixture will turn green/orange/red. The Benedict's solution contains copper (II) ions, which are reduced to a brick red precipitate of copper (I) oxide when the solution is heated. The Aldehyde (-CHO) group in a reducing sugar is the source of electrons that reduces copper (II) to copper (I). Since sucrose doesn't have an aldehyde group, it will not test positive for reducing sugars; it will not reduce the copper II in Benedict's to copper I and change the color of the solution.Fructose does not have an aldehyde group, yet it is reducing, because it gets rearranged to the reducing glucose in basic solution.All monosaccharides and some disaccharides are reducing sugars. Sucrose is one of the disaccharides that is not a reducing sugar.

Would raffinose react with benedicts reagent?
Benedicts reagent tests for reducing sugars, so the question is, is raffinose a reducing sugar. Raffinose is a trisaccharide made up of glucose, fructose and galactose. It is not a reducing sugar because all of its anomeric carbons are bonded, so it will not react with benedicts reagent.
What is an controlled experiment?
A controlled experiment can be used to test almost anything. In a controlled experiment, the scientist (or experimenter) use a control group and an experimental group. The control group has nothing changed about it, and experiment group is changed based on the variable of the experiment. One of the most common uses of controlled experiments is the testing of new medications. In a medical study, a pharmaceutical company usually brings in a group of 100 people. Those people people are randomly assigned to two groups of 50. The experiment group is given the medication being tested, and the control group is given a placebo (a sugar pill). After several weeks, the experimenter can then see the side-effects of the medication, by comparing the differences between the experiment and control groups.
How does your body control blood sugar?
the liver is responsible for the regulation of the sugar level in blood... eating provide the body with sugar... ur liver store this sugar in the form of glycogen... then when ur body needs sugar the glycogen will be broken down into sugar again.... If u want more details u can ask... but please be specific this is a huge topic!!!
Does benedict's solution need heating when testing for glucose?
It is part of the experiment to determine the sugar present... it does not react with non reducing sugar.
Is sucrose is reducing sugar?
No, it is not a reducing sugar.
Does rice have reducing sugar?
Egg yolk has few reducing sugars as found in a biology experiment to find out if reducing sugars such as glucose were found in different foods.
Is maltose non reducing sugar?

Is beet root reducing sugar or non reducing sugar?

Is Cellobiose is reducing or non reducing sugar?
It's a reducing sugar.
Is gentiobiose a reducing or non-reducing sugar?
a reducung sugar since it has an aldehyde group
What is reduced sugar?
A reducing sugar that, in a solution has an aldehyde or a ketone group. This allows the sugar has an reducing agent.
Which sugar is NOT a reducing sugar?
Sucrose
Is gentiobiose reducing or non-reducing sugar?
yes it is a reducing sugar, it has a free anomeric OH group. thus it can also mutarotate
Is splenda a sugar?
No Splenda is not a reducing sugar.
What is the action of strong alkali on reducing sugar?
The action of strong alkali on reducing sugar, reverses the form of sugar back and forth.
