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.
1 All the disaccharides are crystalline solids, soluble in water and fall in two classes, reducing sugar and non-reducing sugars. 2  A number of common disaccharides occur in nature, e.g sucrose,maltose and lactose.ucrose is one of the most important disaccharide commercially and is obtained from sugar cane and sugar beet. Sucrose is a white crystalline solid, soluble in water with melting point 180Â° C. When heated above its melting point, it forms a brown substance known as caramel. Sucrose is dextrorotatory.
