Application

Galactose has been used:
  • as a component of galactosyltransferase labeling buffer.
  • as a supplement in MRS broth for the growth of thermophilic lactobacilli
  • to induce the expression of uncoupling protein (UCP) in yeast transformants

Biochem/physiol Actions

Galactose is a simple monosaccharide that serves as an energy source and as an essential component of glycolipids and glycoproteins. Galactose contributes to energy metabolism via its conversion to glucose by the enzymes that constitute the Leloir pathway. Defects in the genes encoding these proteins lead to the metabolic disorder galactosemia.

The uncoupling protein is one of a family of mitochondrial transport proteins involved in energy metabolism. It dissipates oxidative energy to generate heat, either by catalyzing proton transport directly or by catalyzing fatty acid anion transport, thus enabling fatty acids

The ability to ferment galactose is a major characteristic which can be used to differentiate Lactobacillus helveticus (galactose positive) from Lactobacillus lactis and Lactobacillus bulgaricus (galactose negative). In milk cultures, galactose-positive strains produced d- and l-lactic acid with little galactose

Inflammation is a self-defense response to protect individuals from infection and tissue damage, but excessive or persistent inflammation can have adverse effects on cell survival. Many individuals become especially susceptible to chronic-inflammation-induced sensorineural hearing loss as they age, but the

Metabolic flexibility is an essential characteristic of eukaryotic cells in order to adapt to physiological and environmental changes. Especially in mammalian cells, the metabolic switch from mitochondrial respiration to aerobic glycolysis provides flexibility to sustain cellular energy in pathophysiological conditions.
