What is the structural formula of galactose?
C6H12O6Galactose / Formula
What are D galactose and L galactose?
Chemistry: Galactose is a monosaccharide and belongs to the hexoses that have six carbon atoms (elemental formula: C6H12O6). Long chained galactanes also contain L-galactose which is a mirror-image isomer of D-galactose (L means left-handed in the Fischer projection and D means right-handed).
What are the structural formulas for fructose and galactose?
Glucose, galactose, and fructose are all hexoses. They are structural isomers, meaning they have the same chemical formula (C6H12O6) but a different arrangement of atoms.
What is the number of tautomeric forms in galactose?
Such sugars as D-fructose, D-arabinose, and D-galactose, which exhibit complex mutarotation, are expected to have more than two tautomers present in significant proportions at equilibrium.
What is the formula of mannose?
C6H12O6Mannose / Formula

Is galactose a monosaccharide?
Galactose is a monosaccharide. When combined with glucose (monosaccharide), through a condensation reaction, the result is a disaccharide called lactose. The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and β-galactosidase. The latter is produced by the lac operon in Escherichia coli.
How is galactose formed in Escherichia coli?
