Specification
The L-Galactose is an organic compound with the formula C6H12O6. The IUPAC name of this chemical is (2S,3R,4R,5S)-2,3,4,5,6-Pentahydroxyhexanal. With the CAS registry number 15572-79-9, it is also named as Aldehydo-L-galactose. The product's categories are Basic Sugars (Mono and Oligosaccharides); Biochemistry; Galactose; Sugars; Carbohydrates GAnalytical Standards; GBiochemicals and Reagents; Alphabetic; Carbohydrate Synthesis; Monosaccharides; MonosaccharideSpecialty Synthesis; Carbohydrates; Carbohydrates A to; Carbohydrates GBiochemicals and Reagents; Monosaccharide. Besides, it is white fine crystalline powder, which shuold be stored in a sealed, dry, well-ventilated, lightproof place. It is a type of sugar that is less sweet than glucose. It is considered a nutritive sweetener because it has food energy. It is an epimer of glucose. And it is a polymer of the sugar galactose found in hemicellulose. It can be converted to galactose by hydrolysis.
