Will disaccharides and polysaccharides give positive result for molisch test?
Yes they will. Disaccharides will give a positive result much quicker than polysaccharides, and it also depends on the conditions because they need to be dehydrated by an agent such as concentrated H2SO4 and it so happens that it is much easier to do so on a disaccharide than it is on the polysaccharide
Does isomerism exist in disaccharides?
Yes
Why do disaccharides produce more co2 than monosaccharides?
Disaccharides are larger molecules composed of two monosaccharide units, so they require more energy and enzymes to break them down during metabolism. As a result, the breakdown of disaccharides produces more carbon dioxide as a byproduct compared to the breakdown of monosaccharides.
Is the DNA test result positive or negative?
The DNA test result is positive.
Does isomerism exist in double sugar?
Yes, it does.

Which category of compounds yields a positive result with Clini-test?
The Clini-test primarily detects reducing sugars, particularly glucose, in urine. Compounds that yield a positive result include monosaccharides and some disaccharides, such as lactose and maltose. These sugars reduce copper ions in the test solution, leading to a color change that indicates a positive reaction.
Does isomerism exist in disaccharides?
Yes
What can be learned about a sugar by performing a barfoed test?
The Barfoed test is used to differentiate between monosaccharides and disaccharides based on their reducing properties. In this test, a sugar that can reduce copper(II) ions to copper(I) oxide will result in a red precipitate after heating with Barfoed's reagent (copper acetate in acidic solution). Monosaccharides typically react quickly and yield a positive result, while disaccharides generally do not react under the same conditions, indicating they are non-reducing or require more time or different conditions to react. Therefore, a positive Barfoed test suggests the presence of a monosaccharide.
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.
How are the condition of barfoed's test different from those of nenedict's test?
Barfoed's test is used to distinguish monosaccharides from disaccharides, as it requires a monosaccharide to react within a few minutes. On the other hand, Benedict's test is used to detect the presence of reducing sugars, including both monosaccharides and some disaccharides, by forming a colored precipitate. Benedict's test typically takes longer to develop a positive result compared to Barfoed's test.

Is the DNA test result positive or negative?
The DNA test result is positive.
What occurs when one or more of the enzymes needed to break down disaccharides is adequate?
When one or more is inadequate, the result is carbohydrate intolerance.
What is the sign for multiplication and addition?
If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive.
