(2R)-2,3-Dihydroxypropyl-b-D-galactopyranoside Usage And Synthesis

Description

(2R)-Glycerol-O-β-D-galactopyranoside is a substrate for β-galactosidase, the lactose repressor, the galactose-binding protein, and the β-methylgalactoside transport system. It also serves as a substrate for the third lac operon encoded enzyme, thiogalactoside transacetylase.

Uses

(2R)-Glycerol-O-β-D-galactopyranoside (3-O-β-D-Galactopyranosyl-sn-glycerol) is a good substrate for all three components of the lac operon, i.e. β-galactosidase, the lactose transporter and thiogalactoside transacetylase[1].

Definition

ChEBI: 3-O-beta-D-galactopyranosyl-sn-glycerol is a D-galactosylglycerol. It has a role as a human metabolite.
