[Uses]

1-O-a-D-Glucopyranosyl-D-mannitol is used in the nutritional and biochemical investigations on disaccharide alcohols.
[Definition]

ChEBI: Isomalt is a diastereoisomeric mixture composed of 1-O-alpha-D-glucopyranosyl-D-mannitol dihydrate and 6-O-alpha-D-glucopyranosyl-D-glucitol in a 1:1 ratio. It is used in the food industry as a sugar substitute and in the pharmaceutical industry as a tabletting excipient. It has a role as a sweetening agent, an excipient and a plasticiser. It contains a 6-O-alpha-D-glucopyranosyl-D-glucitol and a 1-O-alpha-D-glucopyranosyl-D-mannitol dihydrate.
[Synthesis]

The synthesis of 1-O-Α-D-glucopyranosyl-D-mannitol dihydrate (hereinafter referred to as 1,1-GPM) is generally a two-step process: 1) the enzymatic conversion of sucrose to isomaltosucrose in the first place, and 2) the subsequent hydrogenation of the iso
