Will disaccharides and polysaccharides give positive result for molisch test?
Yes, both disaccharides and polysaccharides will give a positive result for the Molisch test. The Molisch test detects the presence of any compound that can be dehydrated to furfural in the presence of concentrated sulfuric acid, which includes carbohydrates like disaccharides and polysaccharides.
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.
Does isomerism exist in double sugar?
Yes, it does.
What is the positive result for sakaguchi test?
A positive result for the Sakaguchi test is the formation of a white or yellow precipitate in the presence of arginine or histidine in the test sample. This precipitate forms when ninhydrin (reagent used in the test) reacts with the guanidine group of arginine or the imidazole group of histidine.

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.
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.
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.

What dosage of Vyvanse will result in positive amphetamine result?
Any amount of Vyvanse could result in a positive amphetamine test.
When multiplying a negative number by a positive number is the result going to be negative or positive?
The result will always be negative. Positive X Positive = Positive Negative X Negative = Positive Positive X Negative = Negative
What is a positive integer plus a positive integer?
The result, in this case, is also positive.
Two positive integers and four negative integers are all multiplied together Is the final result positive or negative?
The final result is positive.
