What links the individual monosaccharides in a polysaccharide?

Polysaccharide:

1. Polysaccharides are long-chain carbohydrates formed by repeating units of monosaccharides or disaccharides.
2. The monomers are linked by glycosidic bonds, a covalent bond.
3. This bond is generated between a hemiacetal group of a saccharide with the hydroxyl group of another saccharide.
4. It is formed by a condensation reaction where an -OH group attacks the sugar. The resultant molecule is a sugar compound linked via an ether group.
