Maltose

Structure

The Maltose is Diholoside (figure 1) whose empirical formula is C ₁₂ H ₂₂ O ₁₁. Its molar Masse is, like all the Diholoside S, of 342 g.mol^-1.

Its official name is the α-D-glucopyrannosyl (1->4) D-glucopyrannose . It can be symbolized by Glc-Glc. It is sometimes called di-glucose.

It is the beginning of a biochemical series important, because if a unit of glucose to him is added this one becomes the Maltotriose, then Malto-tetrose, and so on. Molecules with long chain of glucose are called sometimes the maltosides. The maltose is the product of the enzymatic Hydrolyze of the Amidon by a Amylase.

Hydrolize

The maltase (α-glucosidase) hydrolysis the Maltose in Glucose (2 moles of Glc per mole of maltose).

To be able sweetening

Physical properties

Chemical properties

The Maltose is a sugar Réducteur, the carbon hemiacetalic of a glucose is free. Its chemical bond between C1 and C4 is glycosidic hydrolysable : - in acid medium - by a specific enzyme appellée' hydrolase' . Une' mutarotation' is possible on one of two glucoses
