What else can I help you with?
Would you be able to distiguish maltose from lactose in a unknown sample from doing barfoed's test?
Both maltose aswell as lactose are disaccharides, where maltose is made up of two glucose units, whereas lactose is made up of 1 unit of glucose and 1 unit of galactose. Barfoed's test answers only for mono and disaccharides. Presence of red precipitate would indicate a positive result for monosaccharides. Thus doing Barfoed's test does not distinguish between maltose and galactose since both are disaccharides.
Why do crackers taste sweet when you chew?
Bread is carbohydrate, specifically starch. As we masticate, amylase is produced by the saliva which converts starch to maltose which is a sugar. Hence bread tastes sweet on mastication.Bread tastes sweet on mastication (chewing) because the enzymes in saliva begin converting the starch in bread to sugar.
What does the combination of two glucose molecules result in?
The reaction is a condensation reaction so in addition to the disaccharide water is also a product. N.B. glucose + glucose -> maltose + water (not sucrose) glucose + fructose -> sucrose + water
What are the products of hydrolysis of maltose?
When a molecule of lactose is hydrolyzed the monomers that had linked together to form lactose will be pulled away from each other through the addition of lactose. Lactose is made from GLUCOSE AND GALACTOSE, henceforth these two monomers will emerge through the hydrolysis of lactose. Hope this helps...
What is broken down by saliva?
Saliva contains enzymes; in particular salivary amylase. Salivary amylase breaks down starch down in to simple sugars. More precisely, polysaccharides into maltose (a disaccharide). Saliva also starts the process of fat digestion; as it contains salivary lipases also. Enjoy!
What conclusion can you draw when an experimental sample gives both a positive starch and a positive maltose test after incubation?
The positive starch test indicates the presence of starch in the sample which could have been broken down to maltose. The positive maltose test confirms the presence of maltose. Therefore, it can be concluded that the sample initially contained starch which was subsequently broken down to maltose during incubation.
What conclusions can you draw when an experiment sample givs both a positive starch test and a positive maltose test after incubation?
When an experiment sample yields both a positive starch test and a positive maltose test after incubation, it suggests that starch was initially present and has been broken down into maltose during the incubation process. This indicates the activity of amylase, an enzyme that catalyzes the hydrolysis of starch into simpler sugars like maltose. The positive starch test indicates that not all starch was fully converted, while the maltose test confirms the presence of the product of starch breakdown. Overall, this suggests effective enzymatic activity in the sample.
Will Maltose produce a positive Benedict's test?
Yes, maltose will produce a positive Benedict's test because it is a reducing sugar. Benedict's reagent oxidizes the aldehyde or ketone group in reducing sugars, causing a color change from blue to orange/red in the presence of a reducing sugar like maltose.
which of the different carbohydrates test would give a positive result for maltose describe its color change?
h
Is maltose non reducing sugar?
maltose is a reducing sugar ..
Is maltose an oligosaccharide?
Maltose is a disaccharide.
What is maltose dextrin?
dextrine and maltose are byproduct of starch when starch is completely hydrolized it gives dextrin and maltose
How can tests distinguish between glucose and maltose?
Tests can distinguish between glucose and maltose using specific reagents. The Benedict's test can be employed; both glucose and maltose are reducing sugars and will produce a positive result. However, the enzyme amylase can be used to hydrolyze maltose into glucose, which can then be detected using glucose-specific tests like the glucose oxidase test. By assessing the specific reactions and resulting products, one can differentiate between the two sugars.
What the product to the reactants maltose and water?
Maltose and water react to form the maltose solution. A sweet solution!
Is maltose a reducing sugar?
Yes, maltose is a reducing sugar.
What makes maltose?
is a disaccharide formed from two units of glucose. Maltose can be broken down into two glucose molecules by hydrolysis.what are some properties of maltose?Maltose is a malt sugar. The molecular formula for maltose is C12H22O11.
What is the composition of maltose?
The composition of maltose is 2 glucose units. This is because glucose is the 'primary' composition in a monosaccharide and maltose is found in Disaccharide, which is the 'secondary' composition. ~Geek
