α-D-Galactose - Introduction
Α-D-galactose is a monosaccharide widely found in nature. It is a six-carbon sugar with one aldehyde group and five hydroxyl groups. Its chemical formula is C6H12O6.
The properties of α-D-galactose include:
1. Appearance: white crystalline powder or crystal.
2. Solubility: Soluble in water, but insoluble in ethanol and ether.
3. Sweetness: It has a certain sweetness, but it is slightly weaker than the sweetness of glucose.
The main uses of α-D-galactose include:
1. Food additives: as one of the ingredients of food sweeteners, used in cakes, candy and other foods.
2. Biochemistry research: As a reagent in the laboratory, it is used to study the fields of cell biology, biochemistry and pharmacology.
3. Cosmetics and pharmaceutical preparations: one of the ingredients used as moisturizers, antioxidants and anti-inflammatory agents in cosmetics and pharmaceutical preparations.
α-D-galactose has two main preparation methods:
1. By chemical synthesis: can be obtained by chemical synthesis of galactose.
2. Through biotransformation: Other synthetic precursors can be converted into α-D-galactose by the catalysis of microorganisms or enzymes.
Regarding safety information, α-D-galactose does not cause obvious toxicity or harm to the human body under normal circumstances. However, excessive intake may cause indigestion and diarrhea. For some people, such as those who are lactose intolerant or allergic to lactose, the intake of α-D-galactose should be avoided or limited. When using alpha-D-galactose, it should be used in an appropriate amount according to the instructions and guidance of the specific product, and pay close attention to individual reactions.
