Identification
Name:alpha-Lactose
DescriptionAlpha-Lactose is the alpha anomoer of lactose. It is a disaccharide that consists of galactose and glucose joined by an acetal oxygen bridge in the beta orientation Lactose is a sugar substrate that can be readily used by E. coli. The consumption of lactose by E. coli is controlled by the lac operon. The operon includes beta-galactosidase, lactose permease, and thiogalactoside transacetylase. The lactose permease, which sits in the cytoplasmic membrane, transports lactose into the cell. Beta-galactosidase, a cytoplasmic enzyme, subsequently cleaves lactose into glucose and galactose.
