For example, milk sugar (lactose) is a disaccharide made by condensation of one molecule of each of the monosaccharides glucose and galactose, whereas the disaccharide sucrose in sugar cane and sugar beet, is a condensation product of glucose and fructose. Maltose, another common disaccharide, is condensed from two glucose molecules. [7]
Maltose (/ ˈ m ɔː l t oʊ s / [2] or / ˈ m ɔː l t oʊ z / [3]), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond. In the isomer isomaltose , the two glucose molecules are joined with an α(1→6) bond.
Most monosaccharides have the formula (CH 2 O) x (though not all molecules with this formula are monosaccharides). Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose, lactose and maltose) and polysaccharides (such as cellulose and ...
Free sugar – all monosaccharides and disaccharides added to food and naturally present sugars in honey, syrups, and fruit juices (sugars inside cells, as in raw fruit, are not included) Fructose [1] – a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose

Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body , disaccharidases are made mostly in an area of the small intestine 's wall called the brush border , making them members of the group of "brush border enzymes".
Added sugars or free sugars are sugar carbohydrates (caloric sweeteners) added to food and beverages at some point before their consumption. [1] These include added carbohydrates ( monosaccharides and disaccharides ), and more broadly, sugars naturally present in honey , syrup , fruit juices and fruit juice concentrates.
Monosaccharides are a carbohydrate that cannot be hydrolyzed into a simpler carbohydrate and are the building blocks of oligosaccharides and polysaccharides. Oligosaccharides are linear or branched chains of monosaccharides attached to one another via glycosidic linkages. The number of monosaccharide units can vary.
