6⃣🔸#Disaccharides are formed by the condensation of two monosaccharide molecules, with the elimination of a molecule of water. The resulting bond between the two monosaccharides is known as a glycosidic bond. The specific type of glycosidic bond and the two monosaccharides involved determine the type of disaccharide formed.🔹Sucrose is a disaccharide composed of one glucose molecule and one fructose molecule, joined by an α-1,2 glycosidic bond. It is commonly found in sugar cane, sugar beets, and many fruits and vegetables. Sucrose is hydrolyzed in the small intestine by the enzyme sucrase, producing glucose and fructose, which are then absorbed into the bloodstream.🔸Lactose is a disaccharide composed of one glucose molecule and one galactose molecule, joined by a β-1,4 glycosidic bond. It is the primary sugar found in milk and dairy products. Lactose is hydrolyzed in the small intestine by the enzyme lactase, producing glucose and galactose, which are then absorbed into the bloodstream.🔹Maltose is a disaccharide composed of two glucose molecules, joined by an α-1,4 glycosidic bond. It is formed during the digestion of starch and is found in beer and malted beverages. Maltose is hydrolyzed in the small intestine by the enzyme maltase, producing two molecules of glucose, which are then absorbed into the bloodstream.🔸Disaccharides are an important source of energy for the body, and are broken down into their constituent monosaccharides by digestive enzymes in the small intestine. Excessive consumption of disaccharides, particularly sucrose and high-fructose corn syrup, has been linked to obesity and other health problems, and it is generally recommended to consume them in moderation as part of a balanced diet.@Essential_Biochemistry
