True

Explanation:

A disaccharide is a sugar and the general molecular formula of a disaccharide is C₁₂H₂₂O₁₁.

A disaccharide is formed when two monosachharide units are joined by a covalent bond called the glycosidic bond.

The glycosidic bond in a disaccharide is formed by dehydration reaction between the two monosachharide units. The removal of the water molecule results in the formation of the glycosidic linkage.

For example: maltose a disaccharide, is formed when two molecules of glucose are joined by a (1→4) glycosidic bond. As, the glycosidic bond is formed between the carbon 1 of one glucose unit and carbon 4 of another glucose unit.

Therefore, in a disaccharide the two monosaccharide units are joined by a glycosidic bond or linkage.

Therefore, the given statement is TRUE.
