What type of glycosidic bond is present in maltose?

In the 'glycolipids',the two sugars known to occur are glucose and

Consider the following molecules:
Glucose $(K)$,Mannose $(L)$,Galactose $(M)$,$\alpha-Glucose$ $(N)$,$\beta-Glucose$ $(O)$
The correct set of epimer and anomer is respectively:
Epimer - Anomer

What is the $IUPAC$ name of the product $Y$ in the given reaction sequence?

Glucose or sucrose are soluble in water but cyclohexane or benzene (simple six-membered ring compounds) are insoluble in water. Explain.

$D$-Mannose $\overset{HO^{-}}{\longleftrightarrow}$ $D$-Glucose $\overset{HO^{-}}{\longleftrightarrow}$ $(A)$.
Product $(A)$ of the above reaction is:
