Saliva contains the enzyme amylase, which hydrolyses starch into maltose and dextrin. It can also ferment Glucose, fructose, lactose, maltose, sucrose and trehalose. Examples of disaccharides include sucrose, maltose, and lactose. "Corynebacterium minutissimum" consumes carbohydrates such as glucose, dextrose, sucrose, maltose, and mannitol. Corn syrup contains glucose, fructose (monosaccharides), and maltose (disaccharide). Corn syrup, sometimes known as glucose syrup, is a syrup containing dextrin, maltose, and dextrose. The four disaccharides digested in the small intestine are lactose, sucrose, maltose, and isomaltose. Maltitol is a disaccharide produced by hydrogenation of maltose obtained from starch. Lactose, maltose, and sucrose are all compound sugars, disaccharides, with the general formula CHO. Amylase is found in saliva and breaks starch into maltose and dextrin. This includes glucose, fructose, maltose, maltodextrin, etc., but not sucrose. Maltase breaks maltose into two units of either glucose or fructose. Three common examples are sucrose, lactose, and maltose. Common dissacharides, two monosaccharides joined together, are sucrose, maltose, and lactose. Fructose is replaced in the diet by glucose, maltose or other sugars.
