d-galactose

D-Galactose (Alpha-D-galactose) is an aldohexose that exists naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins and is converted enzymatically into D-glucose for metabolism or polysaccharides for storage. It accelerates senescence in invertebrates and mammals and has been used as a model for aging.

6-O-beta-D-Galactopyranosyl-D-galactose, a disaccharide, is a constituent of the polysaccharide backbone characterized by beta-(1→6) glycoside linkages, with a side chain attached to the primary chain through a beta-(1→3) bond.

Galactose 1-phosphate Potassium salt (α-D-Galactose-1-phosphate Dipotassium Pentahydrate) is an intermediate in the galactose metabolism and nucleotide sugars metabolism pathways.

Galactose prevents cognitive deficits in male Wistar rats.

Raffinose (Melitriose) is an indigestible short-chain oligosaccharide, a trisaccharide composed of galactose, glucose and fructose, found in many plants. It can be hydrolyzed by α-galactosidase (α-GAL) to D-galactose and sucrose.

Dulcite (D-Galactitol) is a sugar alcohol that is a metabolic breakdown product of galactose.

D-(+)-Xylose (Wood sugar) is an aldopentose - a monosaccharide containing five carbon atoms and an aldehyde functional group. It has chemical formula C5H10O5 and is 40% as sweet as sucrose. Xylose is also found in mucopolysaccharides of connective tissue and sometimes in the urine. Xylose is the first sugar added to serine or threonine residues during proteoglycan type O-glycosylation. Therefore xylose is involved in the biosythetic pathways of most anionic polysaccharides such as heparan sulphate and chondroitin sulphate. In medicine, xylose is used to test for malabsorption by administering a xylose solution to the patient after fasting. If xylose is detected in the blood and or urine within the next few hours, it has been absorbed by the intestines. Xylose is said to be one of eight sugars which are essential for human nutrition, the others being galactose, glucose, mannose, N-acetylglucosamine, N-acetylgalactosamine, fucose, and sialic acid. . Xylose in the urine is a biomarker for the consumption of apples and other fruits.

D(+)-Raffinose pentahydrate (D-Raffinose pentahydrate) is a naturally occurring trisaccharide composed of fructose, galactose, and glucose, found in various vegetables and grains. It functions as a functional oligosaccharide.

L-Galactose (Galactose, L-) is a natural product that is widely found in plants and animals. L-Galactose has been shown to be a key intermediate in the molecular pathway for the conversion of D-glucose to oxalic acid in Pistia stratiotes.L-Galactose has been shown to be a key intermediate in the molecular pathway for the conversion of D-glucose to oxalic acid.

Stachyose tetrahydrate (D-Stachyose tetrahydrate) is a tetrasaccharide consisting of two α-D-galactose units, one α-D-glucose unit, and one β-D-fructose unit sequentially.

D-Melibiose (Galalpha1-6Glcbeta) is a reducing disaccharide formed by an alpha-1, 6 linkage between galactose and glucose (D-Gal-α(1→6)-D-Glc).

Isocampneoside I, an acylated phenethyl oligosaccharide isolated from Cistanche deserticola (Orobanchaceae), inhibits D-galactose-induced cytotoxicity and protects primary hepatocytes in mice [1].

Lactodifucotetraose (Difucosyllactose), a tetrasaccharide extracted from human milk, consists of one D-glucose, one D-galactose, and two L-fucose molecules [1].

D-Tagatose (D-(-)-Tagatose), a rare natural hexoketose and isomer of D-galactose, occurs naturally in Sterculia setigera gum and is found in small quantities in various foods such as sterilized and powdered cow's milk, hot cocoa, and various cheeses, yogurts, and other dairy products. It can be synthesized from D-galactose by isomerization under alkaline conditions in the presence of calcium. D-Tagatose has numerous health benefits, including promotion of weight loss, no glycemic effect, anti-plaque, non-cariogenic, anti-halitosis, prebiotic, and anti-biofilm properties; it is beneficial for organ transplants, enhancement of flavor, improvement of pregnancy and fetal development, treatment of obesity, and reduction in symptoms associated with type 2 diabetes, hyperglycemia, anemia, and hemophilia.

α-Lactose (hydrate) (α-D-Lactose (hydrate)), the primary carbohydrate in mammalian milk, consists of two sugar units: glucose and galactose, and exists as two anomers, α and β. It serves various roles in the food and pharmaceutical industries, including as a free-flowing or agglomerating agent, and a diluent for pigments, flavors, or enzymes [1] [2] [3].

N-acetyl-D-Lactosamine (N-Acetyllactosamine) is a disaccharide consisting of galactose and N-acetylglucose, which is an important component of various oligosaccharides and can be used as a starting material for the synthesis of various oligosaccharides. N-acetyl-D-Lactosamine may be used as a structural element naturally in various sugar conjugates and can also be used to characterise lectins, which have probiotic effect.
