Catalysis of the transfer of melibiose from one side of the membrane to the other. Melibiose is the disaccharide 6-O-alpha-D-galactopyranosyl-D-glucose and occurs as a constituent of the trisaccharide raffinose or in the exudates and nectaries of a number of plants. Catalysis of the transfer of carbohydrate from one side of the membrane to the other. Catalysis of the transfer of cellobiose from one side of the membrane to the other. Cellobiose, or 4-O-beta-D-glucopyranosyl-D-glucose, is a disaccharide that represents the basic repeating unit of cellulose. Catalysis of the transfer of disaccharide from one side of the membrane to the other. Catalysis of the transfer of lactose from one side of the membrane to the other. Lactose is a disaccharide 4-O-beta-D-galactopyranosyl-D-glucose, and constitutes roughly 5% of the milk in almost all mammals. Catalysis of the transfer of maltose from one side of the membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch. Catalysis of the transfer of sucrose from one side of the membrane to the other. Sucrose is the disaccharide O-beta-D-fructofuranosyl-(2->1)-alpha-D-glucopyranoside, a sweet-tasting, non-reducing sugar isolated industrially from sugar beet or sugar cane. Catalysis of the transfer of a sugar from one side of the membrane to the other. A sugar is any member of a class of sweet, water-soluble, crystallizable carbohydrates, which are the monosaccharides and smaller oligosaccharides. Catalysis of the transfer of trehalose from one side of the membrane to the other. Trehalose is the disaccharide alpha-D-glucopyranosyl-alpha-D-glucopyranoside that acts of a reserve carbohydrate in certain fungi, algae and lichens.
