Carbohydrates and Biomolecules Questions

Mono saccharides
-
Oligosaccharides
-
Polysaccharides
-
Di-saccharides
D
Correct answer
Explanation
Di-saccharides are carbohydrates that are created when two monosaccharides are joined. The creation of a di-saccharide involves the union of two monosaccharides that undergo a process in which a water molecule is removed as part of the union. Like the two monosaccharides that combine to form the single di-saccharide, the carbohydrate is sweet to the taste and tends to dissolve in water with relative ease.

Di-saccharides
C
Correct answer
Explanation
These compounds on hydrolysis yield 2 to 10 mono saccharides . Depending on the number of hydrolytic products formed, the oligo saccharides are further divided in to Di, Tri, Tetra. etc., e.g., lactose(glucose+galactose), sucrose(glucose+fructose).

Polysaccharides
D
Correct answer
Explanation
They are also known as Non -sugars since, they are noncrystalline, insoluble in water, and are tasteless. Polysaccharides are defined as the carbohydrates which on hydrolysis yield more than 10 monosaccharide units . Poly-saccharides have general formula Cx(H2O)y , which is also represented as (C6H10O5)n where n ranges from 40-3000

Sugar + glucose syrup
D
Correct answer
Explanation
Noncrystalline sugar is made from crystalline sugar (i.e., granules) and glucose syrup by heating an undissolved mixture of undiluted crystallized sugar and liquid glucose.

Poly-saccharides
-
di-isaccharides
A
Correct answer
Explanation
Mono-saccharides are the most basic units of biologically important carbohydrates. They are the simplest form of sugar and are usually colourless, water-soluble, crystalline solids. Some mono-saccharides have a sweet taste. Examples of mono-saccharides include glucose (dextrose), fructose (levulose), galactose, xylose and ribose.

D
Correct answer
Explanation
They are also known as Non sugars since, they are noncrystalline, Insoluble in water, and are tasteless. Polysaccharides are defined as the carbohydrates which on hydrolysis yields more than 10 monosaccharide units upon there hydrolysis. Polysaccharides have general formula Cx(H2O)y , which is also represented as (C6H10O5)n where n ranges from40-3000.
