galactose

[Gr. gala (gen it. galaktos )=milk, and Eng. suff. -ose ( Chem. ) (q. v.).] Chem. C6H12O6, also called Arabinose. Obtained along with dextrose by boiling milk sugar [LACTOSE) with dilute sulphuric acid, neutralizing with chalk: filtering, from the filtrate the galactose crystallizes out first. It can be purified from dex trose by being le soluble in absolute alcohol. Ga lactose crystallizes in large rhombic prisms, which melt at 142°; they are very soluble in hot water, insoluble in absolute alcohol and in ether. It reduces four molecules of cupric sulphate. Nitric acid, specific gravity 1'2, oxidizes it into mucic acid. It does not ferment with yeast. By the action of sodium amalgam it is converted into dulcite. ga-lăc-tô-ther-a-pỹ, 8.
