A) zymase
B) lactase
C) maltase
D) diastase
Correct Answer: C
Solution :
Maltose also known as malt sugar is a reducing sugar and gives two molecules of\[\alpha -\]D-glucose upon hydrolysis. In it two glucose molecules are joined by \[\alpha -\]glycosidic linkage between \[{{C}_{1}}\]of the first unit and \[{{C}_{4}}\] of the second unit \[maltose\xrightarrow{maltase}\alpha -D-glu\cos e+\alpha -D-glu\cos e\]whereas: \[\underset{Glu\cos e}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,+\xrightarrow[(from\,yeast)]{zymase}2{{C}_{2}}{{H}_{5}}OH+2C{{O}_{2}}\] lactose is found in milk of mammals \[lactose\xrightarrow{lactase}D-glu\cos e+D-galactose\] Diastase is used to digest starch
