Of especial note is the transformation of maltose by maltase into glucose, and of cane sugar by invertase into a mixture of glucose and fructose (invert sugar); other instances are: lactose by lactase into galactose and glucose; trehalose by trehalase into glucose; melibiose by melibiase into galactose and glucose; and of melizitose by melizitase into touranose and glucose, touranose yielding glucose also when acted upon by the enzyme touranase.
Other forms are: d- and l-gulose, prepared from the lactones of the corresponding gulonic acids, which are obtained from d- and /-glucose by oxidation and inversion; d- and l-idose, obtained by inverting with pyridine d- and l-gulonic acids, and reducing the resulting idionic acids; d- and l-galactose, the first being obtained by hydrolysing milk sugar with dilute sulphuric acid, and the second by fermenting inactive galactose (from the reduction of the lactone of d, l-galactonic acid) with yeast; and d- and l-talose obtained by inverting the galactonic acids by pyridine into d- and l-talonic acids and reduction.
Of the ketoses, we notice d-sorbose, found in the berries of mountain-ash, and d-tagatose, obtained by Lobry de Bruyn and van Ekenstein on treating galactose with dilute alkalis, talose and l-sorbose being formed at the same time.
On reducing the lactone prepared from the inactive acid an inactive galactose is obtained from which l-galactose may be separated by fermentation.
Lastly, when d-galactonic acid is heated with pyridine, it is converted into talonic acid, which is reducible to talose, an isomeride bearing to galactose the same relation that mannose bears to glucose.
Boletus edulis, in the Oriental Trehala and in ergot of rye; melibiose, C12H22011, formed, with fructose, on hydrolysing the trisaccharose melitose (or raffinose), C18H32016.5H20, which occurs in Australian manna and in the molasses of sugar manufacture; touranose, C12H22011, formed with d-glucose and galactose on hydrolysing another trisaccharose, melizitose, C,8H32016 2H20, which occurs in Pinus larix and in Persian manna; and agavose, C12H22011, found in the stalks of Agave americana.
Cooh, is obtained by the oxidation of milk, sugar, dulcite, galactose, quercite and most varieties of gum by nitric acid.
It is soluble in water to an indefinite extent; boiled with dilute sulphuric acid it is converted into the sugar galactose.
Not suitable for individuals who are allergic to cows ' milk protein, suffer from galactosaemia or require a galactose free diet.
galactose oxidase linker showed a clear additive effect over either inhibitor delivered singly.
galactose intolerance should not take this medicine.
galactose solution should be at room temperature at the time the suspension is made up.
Patients with rare hereditary problems of galactose intolerance should not take this medicine.
mannose residues for every galactose residue.
The delivery of dual inhibitors linked by the galactose oxidase linker showed a clear additive effect over either inhibitor delivered singly.
When dairy products are ingested, the lactose reaches the digestive system and is broken down by lactase into the simpler sugars glucose and galactose, which can then be absorbed into the bloodstream.
Other simple sugars include glucose (the form in which sugar circulates in the blood) and galactose (produced by the digestion of milk).
Lactulose is composed of two sugar molecules; galactose and fructose, and should not be administered to patients who require a low galactose diet.
Simple sugars include glucose (the form in which sugar circulates in the blood), fructose (found in fruit and honey), and galactose (produced by the digestion of milk).
Galactosemia is an inherited disease in which the body is unable to metabolize the simple sugar galactose, which is found primarily in dairy products but is also produced by the body.
If left unaddressed, galactose can increase to toxic levels in the body and may lead to damage of the liver, central nervous system, and various other body systems.
Galactosemia is a rare but potentially life-threatening disease resulting from the body's inability to metabolize galactose.
Galactose makes up half of lactose, the sugar that is found in milk.
Persons with galactosemia either have very low levels of or are entirely lack the enzyme that assists the body in breaking down galactose.
The GALT enzyme enables the body to break down galactose into glucose for energy.
Individuals with the classic type of galactosemia lack the enzyme activity necessary to metabolize galactose.
People with the disease are unable to fully break down galactose.
If an infant with galactosemia is given milk, byproducts of galactose will build up in the baby's body, causing damage to the liver, kidneys, brain, and eyes.
Galactosemia is treated by removing foods that contain galactose from the diet.
Foods containing lactose and, therefore, galactose should be avoided.
Because milk and milk products are the most common food source of galactose, persons with galactosemia should avoid ingesting these foods.
It is recommended that persons with galactosemia avoid eating foods with galactose throughout their entire lives.
The goal of dietary treatment is to minimize galactose intake.
However, all persons with galactosemia should limit galactose intake as much as possible.
Parents need to find some of the many listings available that identify the galactose content in foods.
