α-glucose

alpha-D-glucose (α-Dextrose) is a primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.

α-D-Glucose-1,6-bisphosphate is abis-phosphorylated derivative of α-D-glucose that has roles in carbohydrate metabolism.1It is the product of the reaction of glucose-1- or 6-phosphate with glucose-1,6-bisphosphate synthase (PGM2LI) in the conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate.2It is also a cofactor for the bacterial enzyme phosphopentomutase.3,4α-D-Glucose-1,6-bisphosphate has been used in the study of carbohydrate metabolism. 1.Beitner, R.Regulation of carbohydrate metabolism by glucose 1,6-bisphosphate in extrahepatic tissues; comparison with fructose 2,6-bisphosphateInt.

α-D-Glucose-1-phosphate sodium hydrate (Glucose-1-phosphate sodium hydrate) is an intermediate in glycogen metabolism and a precursor in UDP-glucose biosynthesis.

α-D-Glucose 1-phosphate disodium salt is converted into D-glucose-6-phosphate by the enzyme phosphoglucomutase.

4,6-O-Ethylidene-α-D-glucose (Ethylidene-glucose), a derivative of glucose, serves as a competitive inhibitor for the exofacial binding site of glucose transporter 1 (GLUT1), exhibiting a Ki of 12 mM against wild-type 2-deoxy-D-glucose transport.

α-D-Glucose-1-phosphate disodium hydrate is used in various medical and biochemical applications, including as a precursor in the synthesis of glucuronic acid, a cytostatic compound vital for cardiopathic therapy, an antibiotic, an immunosuppressive agent, and a component in circulatory system therapy [1].

Kaempferol 3,7-bis(α-L-rhamnose-D-glucose) (compound 1), a flavonoid glycoside, is found in Euonymus fortunei.

1-Deoxynojirimycin (Moranoline) is a potent α-glucosidase inhibitor, suppressing postprandial blood glucose, thereby possibly preventing diabetes mellitus.

D-Glucose (Glucopyranose) is a monosaccharide, a natural glucose, a sweetener. D-Glucose is the main functional substance of living organisms, and is used as a nutrient in medicine, with diuretic, detoxification and cardiotonic effects.

Sucrose (D-(+)-Saccharose) is a nonreducing disaccharide composed of glucose and fructose linked via their anomeric carbons.

1. Tiliroside (Tribuloside) shows anticarcinogenic activity. 2. Tiliroside shows hepatoprotective activity. 3. Tiliroside shows antioxidant and anti-inflammatory activity, can inhibit neuroinflammation in neurodegenerative disorders. 4. Tiliroside has anti-diabetic effect, are at least partially mediated through inhibitory effects on carbohydrate digestion and glucose uptake in the gastrointestinal tract. 5. Tiliroside and gnaphaliin are antioxidants against in vitro Cu(2+)-induced LDL oxidation in the same order of magnitude compared to that of the reference drug, probucol. 6. Tiliroside enhances fatty acid oxidation via the enhancement adiponectin signaling associated with the activation of both AMP-activated protein kinase and peroxisome proliferator-activated receptor α and ameliorates obesity-induced metabolic disorders.

6-Phosphogluconic acid is a potent and competitive inhibitor of phosphoglucose isomerase (PGI), with an apparent Ki of 0.048 mM for glucose 6-phosphate and 0.042 mM for fructose 6-phosphate as the substrate.

Concanavalin A is a natural product, a phytoalexin (glycan-binding protein). Concanavalin A has antitumor activity and can also induce acute liver injury.

Tormentic acid is a natural product. It has anticancer, anti-inflammatory, anti-atherogenic , anti-allodynic, and hepatoprotective properties,

Isomaltose (D-Isomaltose) is a reducing disaccharide, similar to maltose, but with an α-(1-6)-linkage instead of the α-(1-4)-linkage.

α-Amylase, a hydrolase enzyme, catalyzes the hydrolysis of internal α-1,4-glycosidic linkages in starch, producing glucose and maltose.

Uridine 5′-diphosphoglucose disodium salt (UDP-Glucose sodium salt) is an endogenous nucleotide sugar involved in glycosyltransferase reactions in metabolism. It is an agonist of the P2Y14 receptor (EC50 = 0.35 μM) and can also bind to and activate GPR17, inducing oligodendrocyte differentiation at a maximal concentration of 100 μM.

Palatinose hydrate (6-O-α-D-Glucopyranosyl-D-fructose, Isoma) is a disaccharide having an α(1→6) linkage between D-glucose and D-fructose and is similar to sucrose in its physicochemical properties.
