Because this glycosidic linkage is formed by the OH group on the anomeric carbon of α-D-glucose and the OH group on the anomeric carbon of β-D-fructose, it ties up the anomeric carbons of both glucose and fructose.

Common disaccharides are the grain sugar maltose, made of two glucose molecules; the milk sugar lactose, made of one galactose and one glucose molecule; and the table sugar sucrose, made of one glucose and one fructose molecule.

The bonding is through oxygen to the carbonyl carbon, as in the αα - and ββ -methylglucosides discussed in Section 20-4A, to give acetal or ketal structures. These substances are sometimes simply called glycosides.

This 1 : 1 mixture of glucose and fructose is often referred to as invert sugar because the sign of optical rotation changes, or inverts, during the hydrolysis of sucrose ([α] D = +66.5) to a glucose/ fructose mixture ([α] D = –22.0). This can happen only if the two sugars are joined by a glycoside link between the anomeric carbons of both sugars—C1 of glucose and C2 of fructose.

Key examples include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two glucose units). They play essential roles in energy storage and metabolism. Disaccharides undergo hydrolysis to break into their monosaccharide components.
