1. Product Description
KINTAI is committed to be the best supplier of D-galactose Powder, a reducing monosaccharide found in large quantities in dairy and other non-dairy foods (e.g. fruits and vegetables), which is a component of cerebrosides in the brain nervous system and is closely related to the rapid growth of the brain after birth. Galactose in food is mainly derived from lactose contained in milk; however, infants with lactose intolerance need to add D galactose to their food because they lack the lactase enzyme to break down and metabolize lactose.
In addition, as a basic monosaccharide, D-(+)-Galactose is the basic starting material for the synthesis of many important intermediates. Some drugs contain galactose as an excipient. Low endotoxin D-(+)-Galactose is particularly suitable for biopharmaceuticals. It is a key, chemically well-defined component for optimizing protein production while reducing the formation of lactose and amino acids.

5.D(+)Galactose anhydrous properties
The easiest way to prepare galactose is to hydrolyze lactose to obtain a mixture of equal amounts of D(+)Galactose anhydrousand D-glucose, and then remove D-glucose by fermentation to obtain pure D-galactose, generally in high yield. Galactose can also be prepared from D-lactose by chemical synthesis to grow the carbon chain.
6.Benefits
In general, it has good health effects, can enhance human intestinal absorption ability, improve the health of human intestinal flora, also can promote the absorption of many minerals, also can improve the utilization of human protein, very helpful to the body. alpha-D-galactopyranose has been widely used in food, medicine, biochemical clinical and other fields. Among them, if D(+)Galactose anhydrous can be modified and coupled with anti-cancer, anti-inflammatory and anti-viral drugs, it can improve the quality of the drug effect very well.
7.Application
At present, alpha-D-galactopyranose is mainly used in food, derivative synthesis and biochemical clinical research. In the food field, it is mainly used in the production of D-tagatose and oligogalactose products; in the derivative synthesis, D-(+)-Galactose is used as raw material for synthesis and various organic substances and modified drugs; in the biochemical clinical field, it is used for the construction of D-(+)-Galactose aging model and the study of D-(+)-Galactose-induced aging model in Chinese medicine.
(1) Food field
a. Preparation of D-tagatose
D-tagatose is a new type of low-calorie monosaccharide, which has the functions of lowering blood sugar, improving intestinal flora and preventing dental caries, and is widely used in food, medicine, cosmetics and so on. However, D-tagatose is a rare monosaccharide that exists in very small amount in nature. In order to obtain D-tagatose in large quantity, it can be produced by usingalpha-D-galactopyranose
The chemical method of D-tagatose preparation is to use soluble alkali metal salts or alkaline earth metal salts as catalysts to catalyze the isomerization reaction between alpha-D-galactopyranose and metal hydrides to form metal hydroxide precipitates containing D-tagatose, and then dissolve and neutralize the product by strong acid and separate it.22 The biological method is to use isomerase or microorganisms containing isomerase to catalyze alpha-D-galactopyranose to produce D-tagatose, and the commonly used The commonly used isomerases are L-arabinoid isomerase.
b. Preparation of oligogalactose
Oligogalactose is a functional oligosaccharide, which consists of 1~4 alpha-D-galactopyranose molecules attached to the galactose group of lactose molecule mainly by β-1,4 bonding, and is a hetero-oligosaccharide mixed with glucose and galactose. At present, oligogalactose is widely used in infant milk formula, dairy products and health care products, etc. It has the ability to prevent dental caries, regulate intestinal tract, promote probiotic proliferation and improve autoimmunity. Research shows that alpha-D-galactopyranose as raw material can generate 4 kinds of a-oligogalactose under the catalytic action of a-galactosidase, among which 2 kinds of a-oligogalactose are mutual isomers and 2 kinds of a-oligogalactose trisaccharide.
(2) Synthesis of organic substances
As a reducing monosaccharide with various chemical properties of sugar, alpha-D-galactopyranose is often used as a raw material in organic synthesis, which can form chemical intermediates providing galactose group or directly form the synthesis of target products, and is of great value in the field of synthesis. Among the synthetic intermediates of D-(+)-Galactose, halo-galactose is an important class of galactosyl donors, among which a-fluorogalactose is particularly prominent and is widely used in various instrumental enzymes, such as glycosidases, glycosyltransferases, and mutases catalyzed synthesis reactions. In the synthesis of some mutases, the rate of a-fluorogalactose transglucosylation can reach 100%127.
(3) Drug modifications
Currently, drug research of D-(+)-Galactose has an important position in the pharmaceutical field, and its good performance improves the quality of drugs and has great market prospects in the development of anti-cancer, anti-inflammatory and anti-viral drugs.
