Glucose and fructose are

Which biomolecule forms a starch-iodine complex?

What are $\beta - D - \text{glucose}$ and $\beta - D - \text{galactose}$ known as in relation to each other?

$\beta-D-(-)-\text{fructofuranose}$ is:

$L$-isomer of a compound $A$ $(C_{4}H_{8}O_{4})$ gives a positive test with $[Ag(NH_{3})_{2}]^{+}$. Treatment of $A$ with acetic anhydride yields a triacetate derivative. Compound $A$ produces an optically active compound $B$ and an optically inactive compound $C$ on treatment with bromine water and $HNO_{3}$ respectively. Compound $A$ is ....

Anomers of glucose are defined as:
