"All monosaccharides and most disaccharides can be oxidized. When the cyclic structure opens, the algehyde (-COOH) group is availabel for oxidation. Benedict's reagent contains Cu2+ ion that is reduced. Therefore, all the sugars that react with Benedict's reagent are called reducing sugars. When oxidation of sugar occurs, the Cu2+ is reducted to Cu+, which forms a red precipitate of cuprous oxide, CuO(s). The precipitates colors varies from green to fold to red depending on the concentration of the reducing sugar." Caralyst Pearson Custom Publishing 2011 p.65
What else can I help you with?
Which white powder turns orange in benedicts solution?
The white powder that turns orange in Benedict's solution is glucose. Benedict's reagent contains copper ions which can be reduced by glucose, resulting in a color change from blue to orange-red.
What is oxidized during the oxidation stage of cellular respiration?
Glucose is. In cell respiration, the carbon atoms of glucose are oxidized.
Is glucose oxidized or reduced in cellular respiration?
Glucose is oxidized in cellular respiration to produce energy in the form of ATP. During the process, glucose is broken down into carbon dioxide and water, releasing electrons that are used in the electron transport chain to generate ATP.
Explain what effects the changes in insulin concentration have on glucose mobilization during exercise?
During exercise, changes in insulin concentration can affect glucose mobilization by stimulating glucose uptake in muscles. When insulin levels decrease during fasting or intense exercise, there is reduced inhibition of glycogen breakdown and increased release of glucose from the liver to maintain blood glucose levels. Conversely, high insulin levels during rest or fed state promote glucose uptake by tissues, decreasing reliance on liver glucose release.
Reaction between glucose and copper oxide with lime water?
When glucose reacts with copper oxide in the presence of lime water, a redox reaction occurs where glucose is oxidized to produce carbon dioxide and water. The copper oxide is reduced to copper metal. The lime water is not directly involved in the reaction but can be used to test for the presence of carbon dioxide produced in the reaction.
Why is lactose converted into glucose and galactose during food processing?
Converting lactose into glucose and galactose allows lactose-intolerant people to consume milk products. Glucose and galactose also taste sweeter than lactose so the need for additional sweeteners in flavored milk products is reduced. As glucose and galactose are more soluble, it gives ice-cream a smoother texture. Glucose and galactose can be fermented by bacteria more quickly so the use of these monosaccharides shortens the production time of cottage cheese and yogurt.
Which white powder turns orange in benedicts solution?
The white powder that turns orange in Benedict's solution is glucose. Benedict's reagent contains copper ions which can be reduced by glucose, resulting in a color change from blue to orange-red.
Are glucose and fructose reduced sugars?
Glucose and fructose are reducing sugars.
What is reduced to glucose molecules in carbon reactions?
CO2
Did lactase activity depend upon the presence of cofactors?
Yes, lactase activity depends on the presence of cofactors such as magnesium and zinc ions to function optimally. These cofactors help stabilize the enzyme structure and facilitate the breakdown of lactose into glucose and galactose. Without these cofactors, lactase activity may be reduced.
What molecules supply electrons to an electron transport chain?
Glucose. Glucose is oxidized and oxygen is reduced here.
Reduced growth in plants due to low levels of glucose?
Low levels of glucose can impair plants' ability to produce energy, affecting growth and development. Glucose is essential for providing energy for various biochemical processes in plants, such as photosynthesis and respiration. Reduced glucose levels can lead to plant stunting, reduced biomass, and overall poor plant growth.
What does it mean when glucose is being oxidized?
Oxygen is being reduced.
Is carbon dioxide reduce or oxidized i photosynthesis?
Water is oxidized in the process of photosynthesis.
What type of mutations causes galactosemia?
Galactosemia is primarily caused by mutations in the GALT gene, which encodes an enzyme called galactose-1-phosphate uridylyltransferase. Mutations in this gene result in reduced or absent enzyme activity, leading to the accumulation of galactose-1-phosphate in the body.
What is the prossess of making food from sunlight?
It is called photosynthesis. It is the CO2 reduction into glucose
