In seliwanoff's test how fast does fructose react to give a colored product compared with the other sugar sample?
In Seliwanoff's test, fructose reacts rapidly, typically within 1-2 minutes, to produce a colored product due to its ketose structure. In contrast, aldoses like glucose react more slowly, often taking several minutes to show a color change. This quick reaction of fructose allows for its differentiation from other sugars in the test.

Which sugar is called invert sugar?
when sucrose is hydrolysed it turns into glucose and fructose. fructose is laevo rotatory whereas glucose is dextrorotatory sucrose is also dextrorotatory but amout of laevo rotation of fructose is able to overcome the dextro rotation of glucose. hence the product is laevo rotatory an d reactant dextrorotatory hence sucrose is an invert sugar.
What is a product that results from the process of photosynthesis?
Oxygen
How do you represent a dehydration synthesis as a word equation?
A dehydration synthesis is represented as a word equation by stating the reactants and the product formed. For example, the word equation for the dehydration synthesis of glucose and fructose to form sucrose is "glucose + fructose → sucrose + water."
Why fructose is sweeter than glucose?
Fructose and glucose are both monosacharides. Sucrose is a disaccharide containing fru-glu. Both are sweet, but fructose tastes sweeter per mole. I believe 2 times greater. Which is why glucose from corn starch is enzymatically converted to fructose in the production of high fructose corn syrup and sweeteners. The product will give more sweetness. The lower amount of sugar you need in your food and beverages to satisfy your sweet taste, the better. Cheaper and less calories. The reason why. Your tongue has sweet receptors. Fructose has a more optimal structure for binding affinity to the receptor. Which then elicits a neural response; impulse travels to brain telling you it is sweet and how sweet. Other compounds, non-sugars can also bind to the receptor. e.g. Aspartame (derived from the amino acid asparagine), and some proteins. They are non- to low caloric and low tooth decay.
What role do colored dyes play in mouthwash?
Colored dyes are added to mouthwash primarily for aesthetic purposes, to enhance the visual appeal of the product. They do not have any specific functional benefits for oral health.
Inulin is a polysaccharide composed entirely of fructose units.Which test be used to identify the presence of fructose?
The presence of fructose can be identified using a Benedict's test. Benedict's reagent can detect reducing sugars like fructose by forming a colored precipitate when reacted with the sugar in a heated solution. This forms a qualitative test to confirm the presence of fructose.
What is the substrate for phenolase?
The substrate for the enzyme phenolase is phenol.
What is the end product of fructose?
The liver breaks down fructose in food to yield energy. Fructose is considered the ideal energy source, excess is converted by the liver and stored as fat.
What are reactants and products of the fructose plus glucose equals sucrose reaction?
reactants: fructose and glucose product: sucrose
Which is not an end product of glucose metabolism by either aerobic or anaerobic means?
Fructose
Why fructose give two product on reduction?
Fructose can yield two products upon reduction because it has both a ketone and an aldehyde functional group. When reduced, fructose can transform into two different isomers: D-fructose can be reduced to D-glucose (an aldehyde) or D-sorbitol (an alcohol). The presence of the ketone group allows for the formation of different products depending on the specific conditions and reagents used in the reduction process. This duality in product formation is a result of the structural flexibility of the fructose molecule.
What is the substrate of fructokinase?
FFructose. Fructokinase phosphorylates the fructose molecule to give fructose-1-phosphate as product. 1 molecule of ATP is used and 1 molecule of ADP is released.
What is the end product carbohydrate digestion?
The end product of carbohydrate digestion is mainly glucose together with some fructose, glucose, and galactose. Monosaccharide
What is the end-product of carbohydrates digestion?
The end product of carbohydrate digestion is mainly glucose together with some fructose, glucose, and galactose. Monosaccharide
Is high fructose corn syrup bad?
yes its a product that they take from corn and turn into sugar
What is the by product of sucrose?
The byproducts of sucrose metabolism are glucose and fructose. When sucrose is broken down in the body, it is hydrolyzed into its component sugars, glucose and fructose, which can then be used as sources of energy.
Which sugar is called invert sugar?
