Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Disaccharide sugars are: (1) maltose (2) glucose (3) sucrose (4) raffinoseA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: D
Solution :
Maltose and sucrose are disaccharide sugars. They give two molecule of monosaccharide on hydrolysis. \[\underset{sucrose}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow[{}]{invertase}\underset{glu\cos e}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] \[\underset{fructose}{\mathop{+{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] \[\underset{maltose}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow{maltase}\underset{glu\cos e}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] \[+\underset{glu\cos e}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]
