$D-(+)-\text{Glyceraldehyde} \xrightarrow[(ii) H_2O/H^{+}]{(i) HCN, (iii) HNO_3}$
The products formed in the above reaction are

$D-(+)$-glucose reacts with hydroxylamine $(NH_2OH)$ to yield an oxime. The structure of the oxime is:

The sugar present in $DNA$ is:

Provide the missing details in the following reactions:
$C_{12}H_{22}O_{11}$ $\xrightarrow{A = (?)} C_6H_{12}O_6$ $\xrightarrow{B = (?)} 2C_2H_5OH + 2CO_2$

$A$ diabetic person carries a packet of glucose with him always,because

Given below are two statements:
Statement $I$: Sucrose is dextrorotatory. However,sucrose upon hydrolysis gives a solution having a 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.
