Usage

Uses

Galactinol Hydrate is an α-galactoside of Inositol (I665995), which is the structural basis for a number of signaling and secondary messenger molecules including; insulin signal transduction, cytoskeleton assembly, nerve guidance, membrane potentials, serotonin activity and the breaking down of fats and reducing cholesterol.

Definition

ChEBI: An alpha-D-galactoside having a 1D-myo-inositol substituent at the anomeric position.

Creation of an α-mannosynthase from a broad glycosidase scaffold

α-Mannosides made easy: Mutation of a family-GH31 α-glucosidase that displays plasticity to alterations at the 2-OH position of donor substrates created an efficient α-mannoside-synthesizing biocatalyst. A simple fluoride donor reagent was used for the synthesis of a range of mono-α-mannosylated conjugates using the α-mannosynthase displaying low (unwanted) oligomerization activity. Copyright

Syntheses of penta-O-benzyl-myo-inositols, O-β-L-arabinosyl-(1 → 2)sn-myo-inositol, O-α-D-galactosyl-(1 → 3)-sn-myo-inositol, and O-α-D-galactosyl-(1 → 6)-O-α-D-galactosyl-(1 → 3)-sn-myo-inositol

Two-step conversions of myo-inositol into (±)-2,3,4,5,6- and 1,3,4,5,6-penta-O-benzyl-myo-inositols are described. Starting from these monohydroxy derivatives of myo-inositol, O-β-L-arabinopyranosyl-(1→2)-sn-myo-inositol from Japanese green tea, Camellia sinensis, and O-α-D-galactopyranosyl-(1→3)-sn-myo-inositol (galactinol) as well as its homolog, O-α-D-galactopyranosyl-(1→6(II))-galactinol, were synthesized by way of the in situ activating glycosylation procedure.
