D-Galactose CAS 59-23-4
D-Galactose yog ib qho monosaccharide tsim los ntawm 6 carbons thiab ib qho aldehyde, cais raws li aldose thiab hexose. Ob leeg D-galactose thiab L-galactose tshwm sim lawm. D-galactose feem ntau muaj nyob rau hauv cov mis nyuj ua ib feem ntawm lactose. Lactose nyob rau hauv cov mis nyuj yog tawg los ntawm lub cev mus rau hauv qabzib thiab galactose rau nqus thiab siv.
