D-Galactose

D-Galactose is a natural aldohexose and C-4 epimer of glucose.
Aldehydo-D-galactose is a D-galactose and an aldehydo-galactose. It is an enantiomer of an aldehydo-L-galactose.|Galactose has been used in trials studying the treatment and diagnosis of Hepatitis C, Hepatic Cancer, Wilsons Disease, Diabetic Macular Oedema, and Focal Segmental Glomerulosclerosis, among others. There are even proposals for its use in accelerating senescence in mice, rats, and Drosophila, for its association with ovarian cancer, or even for the potential treatment of focal segmental glomerulosclerosis. Nevertheless, none of these ongoing studies have yet provided formal elucidation for their proposals. As a naturally occurring sugar, it may be found in a number dairy products. Even then, however, it is not generally used as a sweetener considering it is only about 30% as sweet as sucrose. Regardless, although it is predominantly used as a pathway to generate glucose fuel for the human body, galactose is involved as an ingredient in some commonly used vaccines and non-prescription products.|An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.
D-Galactose is a monosaccharide sugar that serves as an energy source and glycosylation component. It is a C-4 epimer of glucose and often used as a source of carbon in culture media. Galactose is a component of the disaccharide lactose and released upon hydrolysis by β-galactosidase enzymes. It is converted to glucose via the Leloir pathway or metabolized via an alternative pathway, such as the DeLey-Doudoroff pathway.
D-Galactose is a natural aldohexose and C-4 epimer of glucose. D-galactose is converted enzymatically into D-glucose for metabolism or polysaccharides for storage. Chronic, systemic exposure to D-galactose accelerates senescence in invertebrates and mammals and has been used as a model for aging. In bacteria, D-galactose is imported by a methyl-galactoside transport system to drive chemotaxis.
