Identify the correct statements.
$A$. Glucose exists in two anomeric forms.
$B$. Anomers of glucose differ in configuration at $C-1$ in cyclic hemiacetal structure.
$C$. Melting point of $\alpha$-anomer of glucose is greater than $\beta$-anomer.
$D$. Specific rotation of $\alpha$-anomer is $+19^\circ$ while for $\beta$-anomer is $+112^\circ$.
$E$. $\alpha$ and $\beta$-anomers of glucose are prepared by crystallization of saturated glucose solution at $303 \text{ K}$ and $371 \text{ K}$ respectively.

Considering the facts that
$I$. sucrose forms glycosidic linkage between $C_1$ of glucose and $C_2$ of fructose,while
$II$. lactose forms glycosidic linkage between $C_1$ of galactose and $C_4$ of glucose.
Choose the correct statement.

The $C_4$-epimer of glucose is:

The change in specific rotation of glucose is due to which phenomenon?

What is the total mass of products obtained when one gram mole of sucrose is hydrolysed (in $\text{ g}$)?
