Maltose is composed of two α−D-glucose units in which C−1 of one glucose is linked to C−4 of another glucose unit.
As there is a free aldehydic group on one of the components of the disaccharides,It is a reducing sugar.
Given below are two statements.
Statement I: Maltose has two α−D−glucose units linked at C1 and C4 and is a reducing sugar.
Statement II: Maltose has two monosaccharides: α-D-glucose and β-D-glucose linked at C1 and C6 and it is a non-reducing sugar.
In the light of the above statements, choose the correct answer from the options Question: given below.

The correct statements are : A. Activation energy for enzyme catalysed hydrolysis of sucrose is lower than that of acid catalysed hydrolysis. B. During denaturation, secondary and tertiary structures of a protein are destroyed but primary structure remains intact. C. Nucleotides are joined together by glycosidic linkage between $\mathrm{C}_{1}$ and $\mathrm{C}_{4}$ carbons of the pentose sugar. D. Quaternary structure of proteins represents overall folding of the polypeptide chain. Choose the correct answer from the options given below :
From the given following (A to D) cyclic structures, those which will not react with Tollen's reagent are : 
Given below are two statements: Statement I: Sucrose is dextrorotatory. However, sucrose upon hydrolysis gives a solution having mixture of products. This solution shows laevorotation. Statement II: Hydrolysis of sucrose gives glucose and fructose. Since the laevorotation of glucose is more than the dextrorotation of fructose, the resulting solution becomes laevorotatory. In the light of the above statements, choose the correct answer from the options given below
