The complex relationships between the components in a system mean that a system is more than simply the sum of its parts. It has properties that are properties of the system a â¦ s a whole and cannot be attributed to any specific part of the system, known as 'emergent properties'.
A disaccharide (also called a double sugar or biose) is the sugar formed when two monosaccharides (simple sugars) are joined. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose.
Some of the common Disaccharides are as follows. 1  Sucrose (table sugar, cane sugar, beet sugar): It is a white, odorless crystalline powder with a sweet taste. 2  Lactulose: It is a synthetic sugar used in the treatment of constipation and in the liver diseases.  Lactose (milk sugar): It is found in milk.
