Essay
Melibiose is a reducing disaccharide that forms D-glucose and D-galactose on hydrolysis.Reaction of melibiose with iodomethane and silver oxide yields an octamethyl derivative,which can be hydrolyzed with aqueous acid to give one equivalent of 2,3,4,6-tetra-O-methyl-D-galactopyranose and one equivalent of 2,3,4,-tri-O-methyl-D-glucopyranose.If melibiose contains an α-glycosidic bond,what is its structure?
